BigPEmu vs JS7800

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.
