description = "The actively maintained Atari Jaguar and Jaguar CD emulator for libretro, continuing the Virtual Jaguar project (originally by David Raingeard of Potato Emulation). No BIOS files are required: the Jaguar boot ROM and CD BIOS images are embedded in the core. Supports Jaguar CD (CUE/BIN, CDI, CHD) with Memory Track saves, JagLink/CatBox network play over TCP or RetroArch netplay, a high-level BIOS that lets most commercial titles boot without a real BIOS image, save states, SRAM, cheat codes, RetroAchievements, and M68K/RISC clock-scale (overclock) core options for framerate-limited games. CHD images must be created with a chdman that writes CHSE session metadata (MAME 2026-08-15 / PR 15886 or later); see the core's jagcd tools. The accurate blitter is SIMD-accelerated (SSE2 on x86, NEON on ARM); the Blitter core option can be set to 'Fast' to trade some accuracy for additional speed on lower-end hardware."
