What was the Atari Jaguar/Jaguar64? A. The Atari Jaguar was the world's first 64-bit home console video game system. Developed after three years of research, manufactured by IBM, the Jaguar was released in Fall 1993, and offered high-speed action, CD-quality sound, and polygon graphics processing beyond most other machines available at the time. Orignally released as the Jaguar, Atari had, at times, referred to the machine as the "Jaguar64" for marketing purposes. For the sake of simplicity in this document, the term "Jaguar" will be used. ============================================================================== Q. What was included when you bought a Jaguar? A. The Jaguar was first sold for $250. It came with the Jaguar itself, one controller, an AC adapter, a television RF switch box, and the CYBERMORPH video game. Later on, the Jaguar was sold without a game, and as time progressed, the Jaguar was sold for $150, then $99. ============================================================================== Q. What happened to Atari, anyway? A. The trials and tribulations of Atari could fill a small book (and, in fact, once did). To summarize VERY briefly, the history of Atari is as follows: 1972 Atari Inc. founded by Nolan Bushnell from a $250 investment. Pong arcade game becomes a smash sensation. 1976 Atari Inc. sold by Bushnell to Warner Inc. for $28 million. 1980 Atari Inc. posts record sales. $2 billion profits annually. Atari occupies 80 offices in Sunnyvale, CA. 1983 Decline of video games and irresponsible spending by Atari Inc. results in record losses ($536 million, up to $2 million daily). 1984 Warner divides Atari Inc. Home division (Atari Corp.) is sold to Jack Tramiel. 1985 Atari Corp. releases Atari ST home computer. 1989 Atari Corp. releases Atari Lynx, the world's first color hand-held video game system (see the Atari Lynx FAQ). 1993 Atari Games becomes Time-Warner Interactive. 1993 Atari Corp. releases Atari Jaguar, the world's first 64-bit home video game system. 1996 Time-Warner Interactive (Atari Games) sold to WMS. 1996 Atari Corp. announces reverse merger with JTS Corporation. 1996 Atari Corp. and JTS connsumate deal on July 31 1996. 1998 Hasbro acquires the rights to Atari Corp.'s name and properties 1999 Hasbro releases their rights to the Jaguar to the public; Atari is reborn as their new home video game label. ============================================================================== Q. What was IBM's role in the Jaguar? A. IBM had a $500 million contract with Atari Corp. to assemble, test, package, and distribute Jaguar units. Manufacturing was done at IBM's Charlotte, NC facility, and the Jaguar was IBM's first attempt at producing a consumer-grade product for an outside vendor. By mid-1994, Jaguar units were also manufactured by Comptronix in Colorado Springs. Jaguar circuit boards were manufactured and assembled by an IBM subcontractor; IBM then cased, tested, and packaged final Jaguar units, which were then sent to Atari. IBM had no participation in the actual design of the Jaguar chipset. ============================================================================== Q. Okay, who did design the Jaguar? A. The primary designers of the Jaguar were Martin Brennan and John Mathieson. They started their own company in 1986 called Flare 1, and designed an original multiprocessor game console. After the system was finished, Flare wanted to "evolve" the system, but needed funding for the job. Atari was contacted, believed in the idea, and agreed to participate. Atari, Brennan, and Mathieson started a new company called Flare 2 to develop the system. As Jaguar development moved along, it became apparent that the machine would leapfrog the then-new systems from Nintendo and Sega (the Super Nintendo and Sega Genesis, respectively), so they decided to bring the machine to light. The entire process took three years, from initial design to production-ready models. The proprietary Jaguar chipsets were manufactured by Toshiba and Motorola. According to Chris Gibbs, Attention To Detail was asked to write technology demos for the Jaguar chipset. The company opted to develop a game instead, resulting in the first Jaguar title, CYBERMORPH. The Flare design was was reportedly based on a project called "Loki," developed by Sinclair Research. Information about the Loki project can be found at http://www.nvg.ntnu.no/sinclair/planet/lokifram.htm ============================================================================== Q. What are the specifications of the Jaguar? A. Physical dimensions: Size: 9.5" x 10" x 2.5" Controls: Power on/off Display: Programmable screen resolution. Horizontal resolution is dependent on the amount of scanline buffer space given to the "Tom" graphics processor. Maximum vertical resolution varies according to the refresh rate (NTSC or PAL). Reportedly, a stock Jaguar (without additional memory) running NTSC can display up to 576 rows of pixels. 24-bit "True Color" display with 16,777,216 colors simultaneously (additional 8 bits of supplimental graphics data support possible) Multiple-resolution, multiple-color depth objects (monochrome, 2-bit, 4-bit, 8-bit, 16-bit, 24-bit) can be used simultaneously Ports: Cartridge slot/expansion port (32 bits) RF video output Video edge connector (video/audio output) (supports NTSC and PAL; provides S-Video, Composite, RGB outputs, accessible by optional add-on connector) Two controller ports Digital Signal Processor port (includes high-speed synchronous serial input/output) Controllers: Eight-directional joypad Size 6.25" x 5" x 1.6", cord 7 feet Three fire buttons (A, B, C) Pause and Option buttons 12-key keypad (accepts game-specific overlays) The Jaguar has five processors which are contained in three chips. Two of the chips are proprietary designs, nicknamed "Tom" and "Jerry". The third chip is a standard Motorola 68000, and used as a coprocessor. Tom and Jerry are built using an 0.5 micron silicon process. With proper programming, all five processors can run in parallel. - "Tom" - 750,000 transistors, 208 pins - Graphics Processing Unit (processor #1) - 32-bit RISC architecture (32/64 processor) - 64 registers of 32 bits wide - Has access to all 64 bits of the system bus - Can read 64 bits of data in one instruction - Rated at 26.591 MIPS (million instructions per second) - Runs at 26.591 MHz - 4K bytes of zero wait-state internal SRAM - Performs a wide range of high-speed graphic effects - Programmable - Object processor (processor #2) - 64-bit RISC architecture - 64-bit wide registers - Programmable processor that can act as a variety of different video architectures, such as a sprite engine, a pixel-mapped display, a character-mapped system, and others. - Blitter (processor #3) - 64-bit RISC architecture - 64-bit wide registers - Performs high-speed logical operations - Hardware support for Z-buffering and Gouraud shading - DRAM memory controller - 64 bits - Accesses the DRAM directly - "Jerry" - 600,000 transistors, 144 pins - Digital Signal Processor (processor #4) - 32 bits (32-bit registers) - Rated at 26.6 MIPS (million instructions per second) - Runs at 26.6 MHz - Same RISC core as the Graphics Processing Unit - Not limited to sound generation - 8K bytes of zero wait-state internal SRAM - CD-quality sound (16-bit stereo) - Number of sound channels limited by software - Two DACs (stereo) convert digital data to analog sound signals - Full stereo capabilities - Wavetable synthesis, FM synthesis, FM Sample synthesis, and AM synthesis - A clock control block, incorporating timers, and a UART - Joystick control - Motorola 68000 (processor #5) - Runs at 13.295MHz - General purpose control processor Communication is performed with a high speed 64-bit data bus, rated at 106.364 megabytes/second. The 68000 is only able to access 16 bits of this bus at a time. The Jaguar contains two megabytes (16 megabits) of fast page-mode DRAM, in four chips with 512 K each. Game cartridges can support up to six megabytes (48 megabits) of information, and can contain an EEPROM (electrically erasable/programmable read-only memory) chip to save game information and settings. Up to 100,000 writes can be performed with the EEPROM; after that, future writes may not be saved (performance varies widely, but 100,000 is a guaranteed minimum). Depending on use, this limit should take from 10 to 50 years to reach. The Jaguar uses 24-bit addressing, and is reportedly capable of accessing data as follows: Six megabytes cartridge ROM Eight megabytes DRAM Two megabytes miscellaneous/expansion All of the processors can access the main DRAM memory area directly. The Digital Signal Processor and the Graphics Processor can execute code out of either their internal caches, or out of main memory. The only limitations are that (1) "jump" instructions in main memory have certain restrictions; the JMP (unconditional jump) command is longword-aligned, while the JR (jump-indexed-by-register) command must be either word- or longword- aligned. And (2) running out of the cache is much faster (up to four times faster) and efficient. Some believe that the inability to jump/branch in main memory makes the main memory feature useless. Swapping data between the caches and the main memory is a quick, low overhead operation, and therefore the main memory is often used as "swap space" for cache code. The RISC compiler included in the latest Jaguar developer's kit produced code that transparently swaps code through the cache. This effectively allowed developers write RISC code without concern for the cache size limits. Compressed cartridge data can be uncompressed in real-time, and ratios of up to 14:1 have been cited. In theory, a Jaguar cartridge can store up to 84 megabytes (672 megabits) of data, though actual results will vary widely (most often, images are compressed, while sound and code are not). Compression is performed with BPEG, an enhanced JPEG image decompression mechanism. BPEG supercedes the former JagPEG algorithm, working up to 10 times faster and with more flexibility. Other Jaguar features: - Support for ComLynx I/O for communications with the Atari Lynx hand-held game system and networked multiconsole games (on DSP port, accessible by optional add-on connector). Networking of up to 32 Jaguar units available. - The two controller ports can be expanded to support "dozens" of controllers - Digital and analog interfaces - Keyboards, mice, and light guns are possible - Expansion port allows connection to cable TV and other networks - Digital Signal Processor port allows connection to modems and digital audio peripherals (such as DAT players) - One megabyte per second serial interface - 9600 baud, RS-232 serial port (accessible with optional interface) - General-purpose I/O bits via the cartridge port - Can accomodate future expansions of different processor types, I/O types, video types, and memory types and/or quantities. ============================================================================== Q. Was the Jaguar really a 64-bit system? A. The question is hard to resolve, largely because the definition of what constitutes an "N-bit" system has not been set. Of the five processors in the Jaguar, only the object processor and the blitter are "true" 64-bit components. Because the blitter and the object processor are in the Tom chip, by extension Tom is a 64-bit chip. Furthermore, the Jaguar also used a 64-bit memory architecture, according to Jez San of Argonaut Software. Some say the Jaguar should be considered a 32-bit system, as that is the maximum register size in the programmable processors (the 68000, the graphics processor, and the DMA sound processor). Others say the Jaguar can be considered a 64-bit system, because 64-bit components are used, and the GPU can access 64 bits of data if required. Again, the lack of an agreed-upon definition serves to complicate the issue. According to Jaguar designer John Mathieson, "Jaguar has a 64-bit memory interface to get a high bandwidth out of cheap DRAM. ... Where the system needs to be 64 bit then it is 64 bit, so the Object Processor, which takes data from DRAM and builds the display is 64 bit; and the blitter, which does all the 3D rendering, screen clearing, and pixel shuffling, is 64 bit. Where the system does not need to be 64 bit, it isn't. There is no point in a 64 bit address space in a games console! 3D calculations and audio processing do not generally use 64-bit numbers, so there would be no advantage to 64 bit processors for this. "Jaguar has the data shifting power of a 64 bit system, which is what matters for games, so can reasonably be considered a 64 bit system. But that doesn't mean it has to be 64 bits throughout." For the record, the opinion of most third party developers and observers is that the Jaguar is indeed a 64-bit system. The emphasis is on the word "system"; while not every component is 64 bits, the Jaguar architecture, as a COMPLETE SYSTEM, is. ============================================================================== Q. The Jaguar used a 68000. Isn't that the CPU? A. Again, quoting from Jaguar designer John Mathieson, "It may be the CPU in the sense that it's the centre of operation, and boot-straps the machine, and starts everything else going; however, it is not the centre of Jaguar's power. ... The 68000 is like a manager who does no real work, but tells everybody else what to do." And... "Atari were keen to use a 68K family device, and we looked closely at various members. We did actually build a couple of 68030 versions of the early beta developers systems, and for a while were going to use a 68020. However, this turned out too expensive. We also considered the possibility of no [Motorola 680x0 chip] at all. I always felt it was important to have some normal processor, to give developers a warm feeling when they start. The 68K is inexpensive and does that job well. I maintain that it's only there to read the joysticks." ============================================================================== Q. How could a graphics processor be the CPU? A. The 64-bit custom graphics chip was a good general purpose RISC unit, but it had been optimized for graphics work. Developers were free to specify which processor(s) to use in a program, as desired. ============================================================================== Q. What kind of special effects could the Jaguar do? A. The Jaguar was capable of doing the following visual effects: - High-speed scrolling (Object Processor). - Texture mapping on two- and three-dimensional objects (GPU and Blitter). - Morphing one object into another object (GPU). - Scaling, rotation, distortion, and skewing of sprites and images (Object Processor). - Lighting and shading from single and multiple light sources (GPU and Blitter). - Transparency (Object Processor). - "Rendering" up to 850 million one-bit pixels/second (35 million 24-bit pixels/second, 26 million 32-bit pixels/second), or 50 million Goroud shaded pixels/second. "Rendering" is believed to mean transferring a pixel from a frame buffer to the screen. - Sprites of "unlimited" size and quantity. Realistically, sprites can be over 1,000 pixels wide/tall, and the number of sprites allowed is limited by processor cycles instead of a fixed value in hardware (Object processor). - Programmable screen resolutions, from 160 to 800 pixels per line. The resolution can be increased even further with additional hardware up to a reported 1350 pixels per line. One of the Jaguar modes is called "CRY mode", which supports lighting and effects in 3D graphics. Red, green, and blue color elements are ranged from 0 to 255, and the lighting level for any pixel can be changed by setting one byte linearly. E.g., the relative proportions of red, blue, and green are indicated with one byte, while a second byte selects an overall intensity of 0 to 255. CRY allows much smoother shading of single colors, but doesn't allow blending between colors as smoothly. Actual graphics performance is hard to measure, as there are no industry- standard benchmarks. Rebellion Software has claimed that the Jaguar can render "10,000 Gourard shaded, large, 65536 color, any shape polygons per second," while still performing other tasks. Presumably this level can be increased further with optimized programming; indeed, some unofficial calculations speculate that FIGHT FOR LIFE may generate between 20,000 to 40,000 texture-mapped polygons per second. A key to understanding the Jaguar's performance is to realize that most effects are accomplished by programming one of the processors to do the job. To perform texture-mapping, for instance, required a developer to write a texture-mapping routine for the GPU and/or blitter, then call it as needed. The general-purpose nature of the Jaguar architecture gave developers a lot of flexibility; unfortunately, the drawback was that software routines for such effects are invariably slower and less efficient than dedicated hardware chips and components. ============================================================================== Q. How come the Jaguar claims to have "32-bit" graphics, when only 24 bits are needed to render 16 million colors? A. The additional 8-bits was for programmers to implement whatever visual effects might be desired. Examples cited include Z-buffering (for polygon graphics) and an alpha channel (for transparency). ============================================================================== Q. Who were the third-party publishers/developers for the Jaguar? A. The following companies have, at one time or another, been announced as official developers, licensees, or publishers for the Jaguar. Note that an official announcement was not an obligation for a company to produce Jaguar-related products; many times, it merely meant that the company made a commitment to "consider" producing product(s) for Atari.

Where can I find secrets, tips, and hints for ? A. A comprehensive list of Jaguar cheats and codes is available from "The Mage," at http://users.aol.com/TheMage1/jaguar/jagcodes.txt or http://members.aol.com/TheMage1/jaguar/jagcodes.txt Clay Halliwell maintains the Atari Jaguar Cheats and Codes FAQ, which he updates regularly. It can be found on the world-wide web at http://www.atarihq.com/jaglynx/jag/jagcheat.txt ============================================================================== Q. Is there a Jaguar emulator available? A. No Jaguar emulators currently exist, and it is the opinion of some Jaguar developers that the system architecture is too complex to be emulated by a current desktop computer using a Pentium or PowerPC processor. On the other hand, "RealityMan" (developer of the UltraHLE Nintendo64 emulator for Windows 95) is reported to be working on a Jaguar emulator. For news updates, visit http://www.emuunlim.com/ ============================================================================== Q. Some of my Jaguar games don't have overlays for the keypads. Where can I get them? A. Not all Jaguar games used overlays for the keypad; some titles didn't use the keypad at all, while others used the keypad, but the developers did not feel that an overlay was needed. Making your own keypads is certainly possible; simply use an existing keypad for a template, draw whatever designs you like, then cut and to fit. Tony Price has made a number of overlays for Jaguar games that didn't include them, as well as dust covers for the keypads. He can be reached by mail at mfmurdock@earthlink.net, or on the world-wide web at http://home.earthlink.net/~mfmurdock/jaguar/jaguar.htm ============================================================================== Q.

Time-Warner Cable's Full Service Network (FSN) plans to offer Jaguar games over television cable lines. The games are downloaded to the customer and played at home, and game instructions can be printed with additional equipment. Details are available from local FSN service providers. ============================================================================== Q. What's the information on the CD-ROM drive? A. A double-speed CD-ROM drive was available. The CD drive has an access time of 210 milliseconds, and has a sustained data transfer rate of 352.8K per second. The CD-ROM drive features a modified data bus interface for access to the Tom and Jerry chips almost directly, allowing for a higher throughput rate on sound and graphics. Storage on a disc is approximately 790 megabytes (6,320 megabits). The CD-ROM drive plugs into the Jaguar's cartridge slot. A pass-through cartridge slot allows cartridges to be used with the CD-ROM attached. Separate memory cartridges allow Jaguar CD games to be saved for later play. The Jaguar CD format is a non-standard format that is not compatable with the ISO-9660 standard. It uses audio-format sectors for data, which allows for 2352 bytes of useable space in each sector. Unfortunately, this leaves no provision for error correction or file system management (though errors are detected by the CD drive hardware). Each disc is copy-protected with encrypted data that is specially formatted to look like an error. Attempts to copy a Jaguar CD will fail because it cannot read the encrypted data, which means the copy will not work. The Jaguar CD allows delivery of full-screen, full-motion video. The CinePak video decompression system has been licensed from SuperMac Technologies. It is a 7K routine in the GPU and can be included in any CD-ROM software that needs it, allowing full-screen video at 24 frames per second. Movie quality pictures can then be overlaid on the screen with computer generated graphics if the game demands it. Time-Warner has licensed a library of film clips from its movies to Atari. The Jaguar CD has "Virtual Light Machine" built in. This program plays audio CDs and generate accompanying color and visual effects that react to the music and sounds. The user can control and select effects with the Jaguar controller. Regular audio CD playback features (volume control, track programming, etc.) are also available. The Jaguar CD can also display CD+Graphics discs. Supplimental cartridges for Kodak PhotoCD and MPEG-1 (Motion Picture Experts Group) compression were considered. The MPEG cartridge would reportedly include extra RAM for buffering and support the whitebook video format. The drive was being manufactured by Philips in the United States. Its dimensions are 6.5" x 10.5" x 3.5", and it weighs 1 pound, 10 ounces. The price was $150, and includes the TEMPEST 2000 soundtrack audio disc, a sampler for the CD game MYST, and two CD-ROM games: VID GRID and BLUE LIGHTNING. ============================================================================== Q. What's the information on the virtual reality headset? A. Atari Corp. and the Virtuality Group had signed a contract whereupon Virtuality would develop virtual reality hwardware and software for the Jaguar. In return, Virtuality would get the rights to port Jaguar VR games to their Virtuality arcade consoles. Though announced, the Jaguar VR was never produced. Unofficial reports conflict on whether the unit was cancelled, suspended, and/or reworked. Reasons given for the inaction ranged from Atari's needs to reassess their investments and focus on core business, to the high suggested retail price of the Jaguar VR headset, to Virtuality's problems in trying to create a mass-market headset that could track head movement fast enough to avoid motion sickness after a few minutes of play. As originally reported, the Jaguar VR package consisted of two components: (1) A lightweight headset (weighs less than one pound). It can be adjusted for fit and works with or without glasses. Game graphics are provided by a single 7", TFT active-matrix color LCD screen, with a resolution of 260 by 400 pixels and up to 65,000 colors. Dual temple speakers provide sound, and a built-in microphone allows player communication in future networked games. A custom optical system projects a binocular image to both eyes; it is aligned at infinity, so focus adjustment is not needed. Two degrees of freedom (left/right and up/down) are available. Field of view is 52 degrees horizontal by 40 degrees vertical. (2) A tabletop-mounted tracking station. The station senses the position of the controller and the headset with "V-Trak" infra-red tracking. The tracking speed is 250 Hz, with a lag time of 4 milliseconds, four times faster than Virtuality's arcade hardware. The tracker has a range of approximately 100 degrees; multiple trackers can be daisy- chained together to provide a complete 360-degree tracking range, but most Jaguar VR games will not require a full 360 degrees. The Jaguar VR equipment was designed to be played while sitting down, so as to avoid injuries. if a player moves out of the tracking station's range, a safety cutoff would have been triggered to suspend the game. Jaguar VR games would have been written for use with the regular controller, as well as a two-button "virtual gun" hand-held joystick. The licensing agreement between Atari and Virtuality permitted authorized Jaguar third-party software developers to write their own VR titles. One product did come out of the Atari/Virtuality agrement. MISSILE COMMAND 3D for the Jaguar provided virtual-reality type play, without the need for special equipment or controllers. The game was later transported to Virtuality's arcade systems. ============================================================================== Q. What's the "Panther"? A. Quick history lesson: Sometime in the late 1980s, Atari Corp. was doing research and development on "next generation" video game consoles. There were two systems, a 32-bit machine called the Panther, and a 64-bit machine called the Jaguar. It is reported that work on the Jaguar was progressing better/faster than expected, so Atari abandoned the Panther to focus their energies on the Jaguar instead. Supposedly, if both machines were fully developed, the Jaguar would have followed the Panther only two years later. Reports of development work on the Panther have been whispered since 1988; some people have erroneously mistaken those rumors to be about the Jaguar. The Panther reportedly was considered a "32-bit" machine by Atari, though for reasons unknown. It featured three chips, consisting of a Motorola 68000 running at 16Mhz, an object processor called the Panther, and an Ensoniq sound processor called Otis, featuring 32 sound channels. The Panther could supposedly display 8,192 colors from a palette of 262,144 colors, and could display 65,535 sprites of any size simultaneously. According to Jeff Minter, the Panther's sprite hardware was very similar to the object processor in the Jaguar, to the point where both had the same limitations. Putting too many sprites on a single scan-line, for instance, would require too much time to draw the line and caused a "tearing" effect in the affected row. Stefan Walgenbach is the proud owner of a working Panther prototype. He has a web page at http://www.HomeComputer.de/ devoted to all sorts of information on the Panther. ============================================================================== Q. What's the "Jaguar II"? A. There's been a little confusion with this topic, since at least two separate machines have been called a "Jaguar II." The first was to have been an integrated Jaguar/Jaguar CD-ROM unit. That project has since been cancelled, making the point moot. The other Jaguar II was Atari's next video-game console. Though rumors were passed, a final design was apparently never produced for even the prototype stage. The following rumors were strongly suggested, however: * Main chipset (codename "Midsummer") developed by Motorola. * Fully backwards compatable with the existing Jaguar. Would have been able to play all Jaguar games and use all Jaguar peripherals. * Processing speed "two to four times faster than the Sony PlayStation." * Full C/C++ development package available. ============================================================================== Q. What's the information on the CoJag and CoJag games? A. To briefly recap, after the Jaguar was released, Time-Warner Interactive (now a subsidiary of WMS/Midway known as Atari Games) licensed the Jaguar architecture for use in arcade games. These systems were called "CoJag" games, and consisted of a Jaguar chipset with additional memory, extra storage, and other architectural changes. Two CoJag games have been released: * Area 51: A light-gun shooting game for two players. The Jaguar's 68000 was replaced with a 68020 or SGI R3K, and ran at 25 MHz. It was also equipped with a four megabytes of RAM and a one gigabyte hard drive. * Maximum Force: Another light-gun shooting game. The 68000 was replaced with an SGI R3K, and came with six megabytes of RAM and a two gigabyte hard drive. While it was rumored that the TWI games "Primal Rage" and "T-Mek" were also CoJag games, this is false; developer Al Vernon has confirmed that those titles did not use any aspect of the Jaguar design or chipset. Finally, funkster@midwinter.com reports that he playtested a third CoJag game, "Freeze," that was never released. Here's a slightly-edited version of his report: "I saw Freeze a couple weeks ago at a local arcade pinball/video game expo. The game made it to field test but didn't do well, so Atari Games axed it early this year. "Freeze was a puzzle game, most closely related to Bust-A-Move or Super Puzzle Fighter II Turbo. You controlled a character at the bottom of a rectangular grid, five wide and eight deep. You had the following controls: move left, move right, throw, and special. You start with a fish in your hands; when you press 'throw,' you threw it into the grid, where it goes up until it hits something. Once your hands are empty, a fish launcher gives you another. "The goal is to get groupings of three or more similarly-colored fish to touch each other, at which point they disappear. Holes are filled in by reverse gravity -- the fish fall up. The game is over when your grid is full of fish or ice. "Here's where it gets original: when you get a group of fish to disappear, you "freeze" a couple of fish on your opponent's field, starting at the top and working down. A frozen fish doesn't work for groupings; fish are unfrozen by making a group nearby. Empty slots get frozen too (the ice is empty). "The 'special' button is for a special attack. When you start the game, you pick a character, which also decides which special attack you get. I didn't play that much of the game, so I don't know how the special works or when you get it. You could play one or two players simultaneously. One player meant playing against computer opponents, along with a bizarre story -- I usually played the monkey character, who was searching for an alarm clock so he wouldn't oversleep, and he asked his opponents for a clock. "The game was pretty fun, and the graphics were nice. It had a look like Trog -- simple 3D, bright saturated colors. It's a shame it didn't fare better in field test." Pictures of the Freeze prototype cabinet and game screen can be found at http://www.cyberroach.com/cyromag/two/woa.htm ============================================================================== Q. Was there a difference in Jaguar games/units sold in different countries? Do I need to keep track of PAL and NTSC versions of a game? A. There is no difference in the Jaguar game software. A properly-written Jaguar game detects PAL or NTSC at startup and changes the playfield size and game speeds accordingly. A properly-written Jaguar game will run at the same speed on either machine. There are no regional or national market lock-outs as there are for other game consoles. The Jaguar consoles themselves were configured differently, according to the country they were sold in. The primary differences were in the video output format (NTSC or PAL) and the power adapters (110 volt or 220 volt). Due to the Jaguar's use of an external adapter, a step-down transformer is not needed. A local PSU can be used so long as it matches these specifications: 1. 9 volt direct current (DC) 2. 1.2 amps 3. Center pin negative The PSUs from old Sinclair computers and Sega Game Gears can be used with the Jaguar without problems. To use an American (NTSC) Jaguar in Europe, you will need a new power adapter and a SCART lead to supply the Jaguar's RGB signals to the TV. Some European TV sets might have also required changing the Jaguar display from a 60Hz frame rate to 50Hz. The 50Hz/60Hz frame rate is set by soldering pads on the bottom of the Jaguar PCB. On an NTSC Jaguar, they're located on the bottom of the PCB near the controller ports. The set labelled "R140" determines between 50Hz and 60Hz. Connect the two points for 50Hz, or leave them disconnected for 60Hz, as follows: 60Hz 50Hz o-o R135 o-o o o R136 o o (Information courtesy of Martin Zimmer, o o R137 o o marz@haari.mayn.sub.de) o o R140 o-o PAL Jaguars sold in Europe have the R140 pads connected with a zero ohm SMD resistor, which can be removed with a soldering iron. It is possible to wire a switch to the points, allowing the Jaguar to be toggled between 50Hz/60Hz. This is mainly useful for PAL Jaguars to play games at the original speed and screen resolution of the NTSC version. Russ Juckes (russ_j@raiden.demon.co.uk) gives these instructions for finding the pads on a European/PAL Jaguar: "Hold the Jaguar PCB with the Joystick ports to the bottom. On the underside of the board, near the joystick ports, and to the left of centre there are four links, the top and the bottom one bridged. (Both with zero ohm resistors). Above them there is another link, with a brown resistor. "The bottom link is the one that needs to be broken. I used a penknife to scratch away the solder, and then a needle-nosed pair of pliers to break the resistor. "The links are *not* labelled in any way. As another guide to make sure you are about to snip the correct link, they are placed directly underneath a chip (which is obviously on the top of the PCB!) so if you use a soldering iron, be careful!" ============================================================================== Q. Hey! My Jaguar makes a quiet hissing sound! What's going on? Is it dangerous? A. Early Atari Jaguars had a rumored problem with the console hissing softly. Atari had cited several reasons for the hissing noise. Some have said that the sound is from the RF generator. The RF shield has holes in it (ostensibly to help air flow and keep the unit cool), and it is believed that the holes produce the noise. Others said the sounds are produced by coil L29 which is responsible for the proper voltage regulation to +10.0V, together with U38. The coil's copper wire vibrates when the current through it changes abruptly, making the hiss. There are two solutions: 1) Use plastic spray or silicone rubber glue to fix the coil's wire. 2) Replace the original Jaguar power-supply with a variable power-source, using 7.5V DC instead of 9V DC (it is not certain whether the Jaguar CD will require 9V DC, which would make this "fix" unworkable with the CD drive). In any case, the "hissing" noise was not dangerous, but merely annoying. It was usually audible only if you put your ear next to the unit and listen closely, and is not interference in the audio output. It is roughly analogous to the buzz made by electric clocks. Most later Jaguars did not have this problem, though a few rare cases have been noted. ============================================================================== Q. My Jaguar comes up with a red screen instead of a game! Is it broken? A. Most often, the "red screen" problem appears after the Jaguar logo has disappeared off the TV screen, and is caused by one of the following: 1. Poor contact between the Jaguar and the cartridge (most likely). Make sure that the cartridge is firmly seated in the cartridge slot, and that contacts are not dirty/dusty. 2. Bent pins in the cartridge slot (rare). This may be caused by rough edges on some cartridges. The pins should be carefully straightened. 3. Defective cartridge (rare). If the red screen only appears with one cartridge but not others, the game may be defective. Exchange it for another. If the Jaguar logo appears without problems, then the Jaguar is probably working fine, and it's only the data transfer between the unit and the cartridge that's causing the problem. ============================================================================== Q. I've heard stories about the Jaguar version of DOOM having network errors when playing with two Jaguars linked together. Are they real? If so, what causes the problem, and can I avoid it? A. There is some truth to the reports -- when linking two Jaguars together for multiplayer DOOM games, network errors sometimes appear which interfere with the gameplay. At worst, the game resets to the start of the current level, which can be annoying if you're in the middle of a heated Deathmatch firefight. The problem stems from several causes. The networking code in DOOM was not thoroughly tested before release, because the game was finished before Atari settled on the final specifications for the JagLink cable (the cable came out almost a year after DOOM did). As a result, this causes some problems due to integration differences. On the other hand, some of the folks playing networked DOOM are using their own home-made link cables, which might not have enough shielding, which also causes errors. There are reports that earlier Jaguar models are more susceptible to errors as well, but the evidence is inconclusive. Recommendations? Set up your Jaguars in an area relatively clean of electromagnetic interference, make sure you are using a well-shielded cable, and cross your fingers. And remember that, even with an occassional networking error, DOOM is still lots of fun with a friend (or foe). ============================================================================== Q: What's the wiring schematic for the Jaguar controller? A: Uwe Roeger (uwer@aragon.bb.bawue.de) reverse-engineered the Jaguar controller port and dissected a Jaguar controller to provide the following circuit diagram: Padport 4 Padport 3 Padport 2 Padport 1 (yellow) (orange) (red) (brown) 74HC244 | | | | ______ | | | | R1 4k7 | | | | | | | | | Padport 6 Pause -------|----------|----------|----------+----- 2| -|)- |18- (blue) | | | | | | | +---|------+---|------+---|------+ R2 4k7 | | | | | | | | | | | | | Padport 10 "A"--|<-+ "B"--|<-+ "C"--|<-+ Opt -|<-+---+----- 4| -|)- |16- (black) | | | | | | | +---|------+---|------+---|------+ R3 4k7 | | | | | | | | | | | | | Padport 11 Right-|<-+ "1"--|<-+ "2"--|<-+ "3"--|<-+---+----- 6| -|)- |14- (grey) | | | | | | | +---|------+---|------+---|------+ R4 4k7 | | | | | | | | | | | | | Padport 12 Left -|<-+ "4"--|<-+ "5"--|<-+ "6"--|<-+---+----- 8| -|)- |12- (l.blue) | | | | | | | +---|------+---|------+---|------+ R5 4k7 | | | | | | | | | | | | | Padport 13 Down -|<-+ "7"--|<-+ "8"--|<-+ "9"--|<-+---+-----11| -|)- |9-- (pink) | | | | | | | +---|------+---|------+---|------+ R6 4k7 | | | | | | | | | | | | | Padport 14 Up --|<-+ "*"--|<-+ "0"--|<-+ "#"--|<-+---+-----13| -|)- |7-- (white) |______| Padport 9: Ground (violet) -- Pin 1,10,15,17,19 on 74HC244 Padport 7: +5 VDC (green) -- Pin 20 on 74HC244 SYMBOL KEY ========== --|<-- 1N4148 Diode + Wire connexion Rx 4k7 Standard resistor, 4700 Ohms, .25 Watts (all resistors are pull-ups; i.e. tied to +5VDC on one end) Padport numbers correspond to those on a standard 15-pin SUB-D plug. The colors of the wires may be different in other versions of the controller. ============================================================================== Q. What's this about a rotary controller? What games use it? How do I make one for myself? A. TEMPEST 2000 has hidden in it an option for a rotary controller (at the "Game Options" menu, press Pause on both controllers to activate the "Controller Type"). No plans for an official Atari rotary controller were announced, but many TEMPEST fans have been trying to build such a controller, to give the game a feel that's close to its arcade original. Andy Light has written instructions for taking a Jaguar joypad and an Atari 2600 Driving Controller and building a rotary controller with the parts. His instructions are condensed below. READ THE INSTRUCTIONS THOROUGHLY BEFORE ASSEMBLY -- there are some areas that are left to the whim of the builder, and advance planning is highly recommended. * * * ANDY LIGHT'S JAGUAR ROTARY CONTROLLER INSTRUCTIONS Parts needed: Atari Jaguar controller Atari 2600 Driving Controller (NOT the paddles) 13 wires, preferably of separate colors Buttons A board or box or shell to mount everything on/in 1. Open the driving controller by removing the two underside screws. Inside is a top-like device or a grey box with three wires coming out of it. This is the encoder. Pull the driving controller's knob off the encoder's shaft, then remove the encoder by unscrewing the nut that holds it in place. Disconnect the wires from the encoder. 2. Open the Jaguar controller. There are four screws on the bottom holding it together, behind the round rubber pads. Inside the controller are two circuit boards connected by a ribbon of wires. The bottom board is for the numeric keypad and is held by two screws. Remove the screws and take out the keypad. 3. Disconnect the wire ribbon from the keypad by melting the solder. CAREFUL! This is delicate work -- get help if you need it. Solder the thirteen wires where the ribbon connection was; do not confuse them. 4. From the left side of the board (the side that says "P2"), I've numbered the wires as follows: 1) Common 5) Button A 9) Button C 13) Down 2) Right 6) Button B 10) Pause 3) Option 7) Button B 11) Up 4) Option 8) Button C 12) Left 5. On the encoder, connect wire #1 to the center terminal, #2 to the right terminal, and #12 to the left terminal. The rotary part of the controller is now finished. 6. How to connect the other controls is up to you. I'm using arcade buttons, a thumbpad, and a switch (to toggle joypad or rotary control) mounted in an Atari 5200 trak-ball controller case. You can mount a joystick, extra buttons, or other features for your own controller. Buttons and empty control boxes are available at stores such as Radio Shack. Wiring for the other signals are as follows: Up - wires #1 and #11 Button A - wires #1 and #5 Down - wires #1 and #13 Button B - wires #6 and #7 Pause - wires #1 and #10 Button C - wires #8 and #9 Option - wires #3 and #4 Because wire #1 has multiple uses, you will either need to string it or split it for each destination. 7. Reassemble and mount everything according to your design. For better spin, you can glue lead fishing sinkers to the inside of the knob, and lubricate the shaft of the encoder with light oil or silicone lubricant. That's it!

Good luck! ============================================================================== Q. I want something better than RF output from my Jaguar. What do I do? A. Atari had an S-Video cable and a Composite video cable available for use with the Jaguar. See the "Peripherals" section for details. If you are willing to build your own, the schematics for the expansion port are as follows: Pinouts for Jaguar Video Cable (view is looking at the rear of the Jaguar) 01A 02A 03A 04A 05A 06A 07A 08A 09A 10A 11A 12A --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- 01B 02B 03B 04B 05B 06B 07B 08B 09B 10B 11B 12B 01A - Left Audio 01B - Right Audio 02A - Audio Ground 02B - Audio Ground 04A - Chroma Ground 04B - Red 05A - Blue 05B - Composite Sync (can also be used 06A - Horizontal Sync for vertical sync) 07A - Green 07B - Luma Ground 08A - Chroma 08B - Luma 10B - Video Ground 11A - +10V power supply 11B - Composite Video S-Video Cable ##\ /---(##- P2 RCA Male (Red) ### / P1 ###>>--(Shielded cable)-----<-----(##- P3 RCA Male (White) ### \ ___ ##/ \---<## P4 4 pin SVHS 3/. .\4 Jaguar Mini-DIN 1| . . |2 Plug Male \_=_/ (front) Conn Pin Signal Conn Pin +----+--------+--------------+----+-----+ P2 Center Right Audio P1 01B P2 Shell Audio Ground P1 02B P3 Center Left Audio P1 01A P3 Shell Audio Ground P1 02A P4 1 Luma Ground P1 07B P4 3 Luma P1 08B P4 4 Chroma P1 08A P4 2 Chroma Ground P1 04A P4 Shell Not Connected P1 N/A Composite Video Cable ##\ /---(##- P2 RCA Male (Red) ### / P1 ###>>--(Shielded cable)-----<-----(##- P3 RCA Male (White) ### \ ##/ \---(##- P4 RCA Male (Yellow) Jaguar Conn Pin Signal Conn Pin +----+--------+--------------+----+-----+ P2 Center Right Audio P1 01B P2 Shell Audio Ground P1 02B P3 Center Left Audio P1 01A P3 Shell Audio Ground P1 02A P4 Center Comp Video P1 11B P4 Shell Video Ground P1 10B For Jaguar owners who wish to use SCART, a Jaguar-to-SCART RGB cable can be made as follows: SCART socket: 20 18 16 14 12 10 8 6 4 2 +--------------------------------------------+ \ -- -- -- -- -- -- -- -- -- -- | \ | | -- -- -- -- -- -- -- -- -- -- | +------------------------------------------+ 19 17 15 13 11 9 7 5 3 1 RGB connection using an 8-pin shielded cable: SCART Signal Jaguar A/V port +-----+---------------+---------------+ 6 Left Audio 1A 2 Right Audio 1B 4 Audio Ground 2A 15 Red 4B 7 Blue 5A 11 Green 7A 16 H-Sync (Blank) 6A 20 Composite Sync 5B 17 Video Ground 10B (connected by cable shield) ============================================================================== Q. How did the ComLynx port on the Jaguar work? Could I connect my Lynx to it? A. The Jaguar does not have a ComLynx port per se, but has a ComLynx signal on the system bus. An expansion port add-on would have made the port available, and developers had announced plans for such accessories. It is possible to daisy-chain multiple Jaguars for multiplayer games into a "Jaguar network". In theory, it would have also been possible to connect Jaguars and Lynxes, though no plans for cross-system software were ever finalized. There was also talk that the Jaguar's ComLynx signal could allow Lynxes to be used as peripherals: software could have been developed to allow Lynxes to be part of a Jaguar game as "smart" controllers. Again, no actual plans were ever announced. For enterprising engineers who wish to build a ComLynx cable for two Jaguars, the following schematics from jonin@netcom.com are available.

All of these wires are on the bottom connector, so that is a good indicater of which way the cable plugs in the Jaguar. Shielded and RF-Choked cables work best. Due to the nature of this connector, it will be hard to shield this cable completely. If you cannot find a 12-contact IDE Card Edge Connector, a 10-contact version can be used. A quick one can be built with no soldering using JDR MicroDevices (Part# IDE10). This is made for ribbon cable, but you can use regular shielded cables with a little work. As long as lines 2, 3, and 6 remain properly connected, there should be no difference. Usage tips: * DO NOT PLUG THIS CABLE IN UPSIDE-DOWN! You may damage internal components if you plug it incorrectly. * TURN OFF BOTH JAGUARS BEFORE CONNECTING. You may damage internal components if you do not. * Since there isn't much strengh in the wires, remove the cable by the connectors. ============================================================================== Q. Agh! My Jaguar is broken! How can I fix it? A. Unforutnately, with the dissolution of Atari Corp., repair or replacement of broken Jaguars is no longer available; Atari/JTS does not have any units remaining for sale or replacement. On the other hand, with the low price of clearance Jaguars today, it isn't expensive to buy a new unit. In Great Britian, Telegames UK will offer to repair your Jaguar for a fee.

Jaguar game development environments existed for the Atari TT030 computer or an IBM PC/compatible. Art development could be performed on any machine, whether a low-end Apple Macintosh or commercial rendering software such as SoftImage. Wavefront's "GameWare" was the official 2D/3D graphics development system; Atari itself used GameWare for in-company development, and registered third-party Jaguar developers could buy GameWare licenses at special discount prices. Estimated price for a developer's package was $9,000 for the TT030 setup, and $7,500 for the PC/compatible platform. The package included a Jaguar development unit, documentation, and development/debugging software. The Jaguar had modified boot firmware to run the development board (the "Alpine board"), and it had a cable coming out to provide signals to the Alpine board that are not normally present via the cartridge connector. CD-ROM developement packages (including the cartridge development kit) were ranged at about $8,000, and were upgradeable from the card-only kit. Software routines packaged with the system included a multi-channel polyphonic FM/Wavetable synth; JPEG decompression; video set-up; drawing primitives; 3D rendering with gourad shading, texture mapping, and camera manipulation. GCC is the primary 68000 C compiler; support for other languages was not available from Atari, but developers were free to use whatever tools they may prefer. The development toolkit ran under DOS, TOS, or Linux. Work was proceeding on a Linux development system using the GNU tools. The centerpiece of the TT030 deveopment platform was DB, an assembly- language level debugging tool. The Jaguar and the TT030 were connected with a parallel cable, and software could be debugged interactively without interfering with the Jaguar's screen display. DB supported the use of scripts and aliases, which simplified the use of complex or common functions. Support for the development packages was primarily provided by Brainstorm (Atari France), who worked closely with Atari Corp. Atari granted final code approval, but did not see the need to "censor" games. Every game was given one man-month of compatibility and quality testing before it was approved. Atari offered technical support via FAX, mail, electronic mail and voice. Atari allowed developers to source their own cartridges, documentation and shells if desired. Jaguar software is encrypted with a proprietary key, thus preventing unauthorized developers from releasing Jaguar software. Cross Products (SNASM) offered an alternative Jaguar Development system. It came with a multiwindowed debugger, assemblers, compilers, and SCSI support, for approximately $3,700. The package allowed for full screen, source level debugging of multiple processors, in C or assembler. This was software only for the IBM PC; the Jaguar development hardware (Alpine board, modified Jaguar, etc.) had to be purchased separately from Atari. Ambitious hobbists have started their own unendorsed Jaguar development efforts, with several "home-brewed" development systems and electronic documentation of the Jaguar's inner workings. Several games have been written for play on the "Jaguar Server" development system (requires some hardware modification to an existing Jaguar, and an IBM PC or Atari ST computer). Information about these efforts may be found on the web at the following sites: - "Jaguar Server" Development system http://hem.passagen.se/isvar/jaguar_server/jserver.html - "Behind Jaggi Lines" Development system http://rghx54.gp.fht-esslingen.de/students/mt/elw5basc/jaguar/ - Jaguar Underground Mailing List http://www.geocities.com/SoHo/1460/ugd.html - Gavin's Jaguar Hardware page http://www.cee.hw.ac.uk/~ceegbs/jaghard.html ============================================================================== Q. Where is the encryption key for Jaguar games? Now that Hasbro has declared the Jaguar an "open system", the key should be available to the public, right? A. Wrong. Even though Hasbro has officially declared the Jaguar to be an "open" system, they have not released the encryption code for Jaguar games because they do not know what (or where) it is. Hasbro's declaration of openness on the Jaguar simply means that developers and hackers are free to use any means they can to develop and sell Jaguar games -- whether they do this by figuring out the encryption key, bypassing the Jaguar's startup checks, or using any other techniques, Hasbro's lawyers will not bother anyone along the way. As of this writing, the unofficial word in the Jaguar community is that the few people who DO have access to the Jaguar's encryption key are trying to make sure that they're "safe" -- that if they release the keys, they won't be prosecuted by some other company for some other reason. But all hope is not lost! According to Scott LeGrand of 4Play, former Atari engineer Dave Staugas has mentioned that the Jaguar's startup encryption check has a "back door" in the software -- a safety measure to be used in case the "real" encryption key was lost. Investigation in this direction is currently continuing, and the latest (unconfirmed) theory is that the encryption (and the back door) works as follows: 1. A 512-bit key is applied to the memory data, and then a 32-bit checksum is used for validation. 2. The bottom 8K or so of ROM memory is filled with a key generated from the cartridge data. When a Jaguar boots, this 8K of data is combined with the ROM data to generate the 32-bit checksum. 3. If the checksum is valid, the cartridge is allowed to run. 4. The "back door" checksum value is: 03D0 DEAD (hex). And yes, it IS a cheeky reference to the Jaguar's then-current competitor... More details about the Jaguar encryption process will be added as it becomes publically available. Scott, Carl, you know where to find me... ==============================================================================
