A JAG file contains a game ROM image created from an Atari Jaguar game. It stores an exact copy of the data dumped from an Atari Jaguar cartridge. JAG files are used to emulate Atari Jaguar games using an Atari Jaguar emulator, such as RetroArch, Phoenix, and MAME.

More Information

You most likely will only encounter a JAG file if you are looking to play an Atari Jaguar game on your computer or mobile device using an emulator. Atari Jaguar games may also be dumped to .J64 files.

NOTE: The Atari Jaguar was a 64-bit video game console released in 1993. It was a commercial failure and helped put Atari out of the home video game console market. However, the console has since gained a cult following, which has led to the rise in emulators supporting Atari Jaguar games.
