kat5200 is a free, open-source emulator for the Atari 5200 SuperSystem and Atari 8-bit computer families, including the Atari 400, 800, 800 XL, and 800 XE. It is aimed at people who want one application for these systems across Windows, macOS, Linux, and Android. Its graphical interface covers ROM library scanning, searchable launching, system configuration, per-ROM overrides, and emulator state management. Support for cartridges, floppy disks, cassettes, and executables gives it a broad software format range.

The standout strength is control over individual games and systems. Users can save and load states through quick-save slots and named state files, while controller input can be remapped with multiple bindings. Keyboard, joystick, gamepad, mouse, and trackball input are supported. Visual options include an NTSC artifacting filter and shader support, giving Atari-focused users more control over how software is presented. This makes kat5200 a strong fit for varied Atari libraries and mixed input setups rather than a narrowly focused single-system emulator.

Setup requires users to supply the required BIOS and software separately because kat5200 does not include copyrighted BIOS or game ROM files. That adds an initial preparation step for anyone expecting an out-of-the-box library. Android distribution also uses direct APK installation instead of the Play Store. Choose kat5200 if you want open-source, cross-platform coverage for Atari 5200 and Atari computer systems with per-ROM controls and save states. Choose another option if you prefer a store-based Android installation or software that includes the required system files.
