Atari 5200DS vs Stella

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.

Stella is free, open-source software for playing Atari 2600 VCS games on a computer. It runs on Windows, macOS, and Linux under the GNU General Public License. It supports A26, BIN, and ROM images, including files in ZIP archives, as well as Supercharger games. Atari and other controllers can be emulated with a keyboard, joystick, or mouse; real Atari controllers can be used through Stelladaptor and 2600-daptor devices. Emulation features include cycle-exact TIA video and sound, stereo support, and dynamic sound resampling. Stella provides save and load for system states, automatic timeline recording, and high-score saving. Display support covers NTSC, PAL, and SECAM, with customizable CRT-style filters and bezels. A debugger offers static analysis using the Distella disassembler and runtime analysis of code, graphics, and data. The project names homebrew developers among its intended users. General requirements include SDL 2.0.14 or later and 256 MB of RAM for emulation; stable downloads include Windows binaries, a macOS disk image, an Ubuntu 22.04 DEB package, and source code for all systems.
