Atari 5200DS vs BigPEmu

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.

BigPEmu is an Atari Jaguar emulator for Windows, Linux, iOS and macOS. Its maker says it can run every game in the Jaguar retail library, and that default settings run the library at full speed on almost any x64-capable processor. Jaguar CD support covers the retail disc library, Memory Track and VLM, with a virtual disc system and audio loopback option. Players can save states and record deterministic movies from controller inputs. Visual options include customizable postprocessing shaders, native HDR and per-game profiles, alongside fast-forward and rewind. Input support covers analog, driving and rotary controllers, Team Tap and other devices recognized by the host system. Network features support JagLink games and synchronized states for two to eight players. Scripting includes tasks such as breakpoints and memory access. The desktop download is a zip archive that runs without installation and has an in-app update option. The maker notes that imperfect timing can make some software run too fast at default settings.
