kat5200

Summary

kat5200 is a free emulator for playing games from the Atari 5200 and Atari 8-bit computers on personal computers. It supports Atari 5200, Atari 400, Atari 800, Atari 800 XL, and Atari 800 XE systems, with builds listed for Windows, macOS, Linux, and Android. The emulator does not include game ROM images or BIOS files, so those must be obtained and configured separately. Controls can come from a game controller, keyboard, or mouse, and multiple input entries can be assigned to an emulated function. Players can save different input profiles and associate them with games in the Launcher. The Simulate Analog option can help when using a keyboard or digital controller for games that expect controller-axis positions. Initial setup can scan a ROM directory and offers options for mouse-as-trackball, mouse-as-paddle, and two-stick games. Version 1.0.0 uses TOML configuration and supports profiles per ROM. The Android version is distributed as an APK and must be sideloaded rather than installed through the Play Store.

Who it is for

kat5200 suits people who want to play Atari 5200 or 8-bit computer games on Windows, macOS, Linux, or Android. Users need to obtain and configure ROMs and BIOS files themselves.
