BigPEmu vs Íris Emulator

BigPEmu is an Atari Jaguar emulator for Windows, Linux, iOS and macOS. Its maker says it can run every game in the Jaguar retail library, and that default settings run the library at full speed on almost any x64-capable processor. Jaguar CD support covers the retail disc library, Memory Track and VLM, with a virtual disc system and audio loopback option. Players can save states and record deterministic movies from controller inputs. Visual options include customizable postprocessing shaders, native HDR and per-game profiles, alongside fast-forward and rewind. Input support covers analog, driving and rotary controllers, Team Tap and other devices recognized by the host system. Network features support JagLink games and synchronized states for two to eight players. Scripting includes tasks such as breakpoints and memory access. The desktop download is a zip archive that runs without installation and has an in-app update option. The maker notes that imperfect timing can make some software run too fast at default settings.

Íris Emulator is a free, open-source emulator for Atari 2600, Atari Lynx, and Atari Jaguar games on 64-bit Windows 10 or 11. The Atari 2600 core emulates the 6507 CPU and TIA, with NTSC, PAL, and SECAM support and several cartridge mappers. Lynx emulation covers the 65C02, Mikey, and Suzy, with LNX cartridges, HLE boot for homebrew, and optional user-supplied boot ROM support for commercial games. Jaguar support includes .j64 and .jag cartridges, RF Cable and S-Video filters, upscaling to 1080p, and Auto, 4:3, or 16:9 display ratios. The interface offers cover-art browsing, a first-launch wizard, fullscreen mode, remappable keyboard and gamepad controls, and ten save-state slots. VST3 audio processing uses a reorderable chain and master gain. Optional Discord Rich Presence requires the Discord desktop app. ROMs and BIOS files are not included.
