NeoCD-Libretro vs NeoDS

NeoCD-Libretro has no write-up on Specifiction yet; its figures are above.

NeoDS is a Nintendo DS emulator for NeoGeo AES and MVS games. It emulates the M68000 and Z80 CPUs, graphics, ADPCM and PSG audio, as well as NeoGeo protection and encryption. NeoDSConvert converts NeoGeo ROM sets into .neo files, and the emulator uses the same ROM sets as MAME. The documented setup requires a Nintendo DS Lite and a DLDI-compatible flash card. A Slot-2 flash card with RAM is optional and can improve the speed of some games. The emulator supports button remapping, normal or scaled video, CPU underclocking, and saving configuration and SRAM to the flash card; its graphical interface is operated with a stylus. It does not emulate FM audio, raster effects or multiplayer, and some timings are not very accurate. The repository describes the project as a fork of a 2008 NeoDS release being updated to 2026 MAME sets. The emulator is free to use for non-commercial purposes; save states appear in the README’s TODO list rather than as a supported feature.
