Atari 5200DS vs kat5200

Atari 5200DS is a free emulator for Atari 5200 games on Nintendo DS-family systems, including DS, DSi, DSi XL, and DSi LL. Its stated coverage includes the original 69 commercial releases and a couple hundred homebrews, hacks, and prototypes. Bankswitching cartridges up to 512K are supported, including Bounty Bob Strikes Back. Players can mark games as liked or loved, and the emulator saves up to 10 high scores per game to the SD card. Some controls are adjusted for particular games: Frogger and Q-Bert are patched for button movement, while Robotron can use ABXY to shoot and the d-pad to move. The emulator requires NTSC-compatible ROMs in a52/bin format and recommends the original 4-port 5200.rom BIOS for full compatibility. A built-in replacement BIOS works for some games with limited compatibility. The README says games run at full speed on DSi or newer systems, though complex conversions may lag on DS Lite or Phat. Quest for Quinta Roo will not start because of a known key debounce issue. Version 3.9 was released April 8, 2026.

kat5200 is a free emulator for playing games from Atari 5200 and Atari 8-bit computer systems on a personal computer. 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 users must obtain and configure them separately. Controls can use a game controller, keyboard or mouse, and multiple input entries can be assigned to an emulated function. Users can save different input profiles and assign them to games in the Launcher. The Simulate Analog option can help when a game expects controller-axis positions but the player uses a keyboard or digital controller. Initial setup offers ROM-directory scanning and options for trackball, paddle and two-stick games. Version 1.0.0 uses TOML configuration and adds per-ROM profiles. The Android version is provided as an APK, not through the Play Store, and must be sideloaded.
