The '''Atari Jaguar''' (AJ) was a fifth generation home video game console released by [[wikipedia:Atari|Atari]] in 1993. It had a Motorola 68000 CPU and 2 custom RISC CPUs. It has 2MB of RAM. Despite the intense marketing efforts by Atari, the Jaguar is, in fact, a 32-bit console with a 64-bit bus. The system's convoluted architecture didn't help matters either, which led most developers to just use the 68000 for gameplay logic. The console would prove to be the final home console release for Atari until the [[Atari VCS|VCS]] in 2021. There was also a CD addon called the Atari Jaguar CD (AJ-CD).

In 2000, the console's patents were released into the public domain, which effectively made it an open system - the homebrew scene for the Jaguar is particularly active compared to its competitors (e.g. the [[3DO emulators|3DO Interactive Multiplayer]] and [[Sega Genesis emulators|Sega 32X]]) as a result.

===Comparisons===
;[[BigPEmu]]:The newest and most compatible Atari Jaguar emulator, boasting 100% compatibility, and features Jaguar CD, Jaguar VR and JagLink support.
;[[Virtual Jaguar]]: An open-source emulator based on the original by the same name. Use the link given as "[https://buildbot.libretro.com/nightly/ libretro core]" on this page and choose the most current version from there.
;[[Phoenix (emulator)|Phoenix]]:About 95% of Jaguar titles are compatible. No support for AJ-CD/AJ-VR games. The PC version of the emulator is only available in Russian, but an [http://www.rlauncher.com/forum/index.php?threads/help-with-3do-phoenix-2-8.4160/ English patch] is available.
;[[MAME]]:Preliminary support. Some games boot but the emulation is far from perfect.
;Project Tempest:Was the first ever working Atari Jaguar emulator. It emulates some games, but most have issues. As its name suggests it was primarily made for Tempest 2000, with other games as secondary goals. Project Tempest is the first Jaguar emulator that supports Jaguar CD games, but only two are compatible; Primal Rage and Baldies (the latter has sound distortion though). It has not been updated since 2004.
;[[Phoenix (emulator)|IrataJaguar]]: The Phoenix emulation project is released as separate emulators for Android, this is the Jaguar version. Identical compatibility to PC version according to the author. Requires fast 64-bit CPU 2GHz+ or better for full speed.
