Atari 5200DS vs Holani

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.

Holani is a free, open-source Atari Lynx emulator for Linux and Windows, released under GPL-3.0. Its cycle-stepped 65C02S emulation began from the design idea of chips’ 6502. The project can also operate as a library for other frontends and links to a libretro core for official games and homebrews. Holani-retro works with libretro frontends such as RetroArch, providing save and load states plus RetroArch cheats. Holani-gtk is a GTK4 frontend for loading cartridges and overriding ROMs. Holani-min provides a command-line interface with button mapping, display filtering, mute, and Comlynx options; multiple instances can connect through Comlynx. The project also lists holani-debug, an Atari Lynx debugger. Holani embeds the Free Lynx Boot ROM and BLL uLoader blobs, so no BIOS is required. GTK builds require Rust, Cargo, and GTK4; Windows libretro use requires the Microsoft Visual C++ 2015 Redistributable.
