Atari 8-bit emulator (400/800/XL/XE/5200). It covers the following systems: Atari 800, Atari5200, Atari7800.

1. Installation

  1. Download the latest version from the project's official website.
  2. Extract the archive into a dedicated folder.
  3. Launch it once: it will create its configuration and subfolders.

2. System files

This emulator relies on files taken from the original machine. Extract them from hardware you actually own.

Files expected according to our listing:

  • ATARIXL.ROM
  • ATARIBAS.ROM
  • 5200.ROM

Indicated location: bios/

Atari BIOS required

3. Supported formats

.atr .xfd .dcm .atx .a52

4. Good to know

  • These machines often boot to a command prompt: the game is launched via a command, not a menu.
  • Emulation speed matters: if it's too fast, the software becomes unplayable. Look for the speed or cycles setting.
  • The keyboard is the main input device; the emulated layout may differ from your own.
  • A setting that works well for one system won't necessarily suit another: adjust on a case-by-case basis.

5. Not working?

  • Refuses to start or black screen → a system file is missing, misnamed, or not in the expected location.
  • File rejected → its checksum doesn't match the expected one; the dump is probably incomplete or comes from a different model.
  • The game doesn't show up → check that its file extension is among the formats listed above.
  • The software runs too fast or too slow → adjust the emulation speed before anything else.
