Useful files, tools and links for Jaguar development


Recommended Posts

This topic is a repository for all files, tools and links that are useful for Jaguar development. Click on the titles to download the files.
If you think something is missing, find a broken link, or have a suggestion to improve it, don't hesitate to post.

(work in progress, unsorted as of now)

Developer documentation (contributed by Starcat and Jon Matthieson)
These are scans of the paper documentation which was included in the Jaguar's SDK. They are believed to be the most up-to-date version available.
Beware : the archive also includes the Techref v8 file made available by John Mathieson in 2001 ; while it is more convenient to use, it appears to be an older version.

JAGUAR.INC is the include file which contains hardware registers and constants definitions. You'll need it to program in assembler or C.
This version has a changelog dated 05/16/1995 and is believed to be the latest one.

JagView (contributed by dox)
JagView is an utility to find and display uncompressed Jaguar pictures embedded in a ROM file (or as separate files). 8-bit, CRY and RGB formats are supported.
Beware : it is known to display slightly wrong colors in some circumstances.

Jagfiles (contributed by Curt Vendel)
Lots of source code from games, mechanical drawings, various Atari documentation, etc.

Thanks to Glenn Bruner for providing the files!

Some files are unfortunately missing.

Universal cartridge header (contributed by Glenn Bruner)
The cartridge header that can be added in front of any ROM code to allow it to run on non-modded Jaguars.

MPEG cartridge documents (contributed by Glenn Bruner)
Technical documents related to the MPEG 1 decoding cartridge that Atari planned (but never released).

Adding a rotary on a standard Jagpad

Cartridges mechanical drawings / dimensions

Fastboot header for carts (contributed by Tursi)
A special header for cartridges that speeds up the boot process.

The Jaguar Server home page
A mirror of Roine Steinberg's Jaguar Server page. (A few images are missing, unfortunately)

Flare II Jaguar technical reference manual (pre-Atari, 1992)
For archeology buffs, the oldest version of the docs.

Freescale (formerly Motorola) is the manufacturer of the 68000 processor in the Jaguar. You'll find the official technical documentation on this page.

Matthias Domin's Jaguar page
Very complete webpage with extensive information about the hardware aspects of the Jaguar. Includes the Jaguar hardware schematic, cartridge schematics, and information about BJL and other hardware modifications, the JagLink and compatible devices, analog controllers, light guns, mice, rotary controllers, CD encryption, cartridge EEPROMs, and more.

Home of the BJL development kit. Includes the BJL ROM image, uploader programs for DOS, Linux and the Atari ST/TT/Falcon, and various demos with sources.

Hill Software (local mirror)
You can find the original Jaguar SDK here, as well as ready-made development environment for Windows, Linux and MacOS X. There is also a CD version of the BJL ROM and a GUI frontend for the Skunkboard tools.

The Removers
Development environment and support libraries to create Jaguar programs easily in C, with examples.

Swap d0's development tools
Jaguar development suite for BeOS, with sources : BJL loader, assembler, debugger and disassembler. There's also an image compression routine.

ray's 16/32 bits Atari page
CRY image viewer for the ST (look in the 'Miscellaneous' part). There is also a lot of code which is not Jaguar-specific but nonetheless very interesting (data packing, wavelet image compression, 3D algorithms, etc.).

Reboot projects
Universal Loading System (convert any BJL program into a self-bootable CD in just a few minutes), CD encryption with the Skunkboard, Atari ST version of the BJL uploader patched to work correctly with large files, Jagtopia (CD-based encryption bypass).

The Jaguar Underground Documentation
The first independent attempt at documenting the Jaguar. Pretty much obsolete now that the official docs are available, but you never know...

The Jaguar Server home page
As the title says, this is the home page for the old Jaguar Server computer-to-Jaguar link. It's been superseded by BJL for a long while, and the link is provided for historical purposes.

No Fragments 9: Jaguar Freeware
Random public Atari Jaguar files, some are development-related. The whole CD is also available as an ISO image.

A pretty fast Jaguar emulator, but not very accurate. It is no longer developed. Note : if something doesn't run with Project Tempest 0.95, try the 0.5 version from this page instead : it works better in some cases.

Virtual Jaguar
(Windows binaries)

A more accurate but much slower Jaguar emulator. Still developed, but not updated often.

Another emulator ; it was considered abandoned since 2001, but a new version has been released by its author in June 2011.

Good thing you mentioned the archive's name, because otherwise with source code names such as SUCK.S and PUSSY.S one might get the wrong idea :P


Seriously, was that thing ever made and/or works?

Atari got at least a few prototypes made. Glenn Brunner has one. More info here.

Would you be willing to add my fastboot header for carts? I had it at JS2, but since that's down... ;) It has just 2 blocks to decrypt instead of 10 so starts in 1 second instead of 5. I also had a tool to replace the boot header on any ROM image with it. (It was originally one block, but that's not compatible with the JagCD).


Downside of it is that it doesn't verify the entire cartridge, but, neither does the common universal header, so I figured that might be okay. ;)
