In their own words
Virtual Jaguar
Virtual Jaguar libretro is a free, open-source emulator core for Atari Jaguar cartridges and Jaguar CD media. It is designed to run through a libretro frontend such as RetroArch, not as a standalone emulator. The core emulates the Jaguar’s 68000, GPU, DSP, Object Processor, and Jaguar CD hardware. It accepts cartridge formats including .j64, .jag, .rom, .abs, .cof, .bin, and .prg, plus Jaguar CD CUE, CDI, and CHD images. Console and Jaguar CD BIOS images are embedded, so external BIOS files are not required. Through its frontend, the core supports save states, cheats, rewind, run-ahead, netplay, shaders, controller remapping, and fast-forward. Optional settings include true-color rendering, 2× internal resolution, overclock controls, and adjustable CD read speed. Link-cable emulation supports TCP transport and a multi-peer hub. The project notes that the blitter is not fully cycle-accurate, GPU/DSP pipeline hazards are not modeled, and some titles can run too fast. Listed platforms include Android, iOS, Linux, macOS, web, and Windows.
