BigPEmu vs EMU7800

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.

EMU7800 is a free emulator for the Atari 7800 ProSystem and the backward-compatible Atari 2600 Video Computer System. It runs on Windows, Linux, and macOS and supports saved game states. The maker says it runs on Windows 11, and its Windows installer does not need administrator permission. Windows users can connect Stelladaptor, 2600-daptor, 2600-daptor II, and Xbox 360 controllers. Saved game state is kept in the user profile at %USERPROFILE%\.emu7800savedgames. The project lists Linux ARM and ARM64 targets using SDL3; Linux systems may need SDL3, SDL3 image, and SDL3 TTF installed. Its macOS x64 and ARM64 targets are described as experimental and untested. Building from source requires the .NET 10.0 SDK and Git. The project was originally completed in 2003 as a .NET programming exercise, is licensed under GPL-2.0, and is maintained as a non-commercial endeavor. The current release listed is v5.7.0.0, released December 31, 2025.
