EMU7800
What it is
EMU7800 is a free emulator for the Atari 7800 ProSystem and backward-compatible Atari 2600 Video Computer System. It is available for Windows, Linux, and macOS and supports saved game states. The maker says it runs on Windows 11, and the Windows installer does not need administrator permission. Windows controller support includes Stelladaptor, 2600-daptor, 2600-daptor II, and Xbox 360 devices. Saved game state is kept in %USERPROFILE%\.emu7800savedgames. The project lists Linux ARM and ARM64 targets using SDL3; Linux systems may need SDL3, SDL3 Image, and SDL3 TTF installed. The listed macOS x64 and ARM64 builds are experimental and untested. Building from source requires the .NET 10.0 SDK and Git. EMU7800 was originally completed in 2003 as a .NET programming exercise, and the maker describes it as a non-commercial project maintained to the present day. The repository identifies its license as GPL-2.0. Users can send feedback to [email protected].
