In their own words
MVSPSP
MVSPSP is a free, self-hosted emulator for Neo-Geo MVS and AES systems, with PSP as its supported platform. The repository is public under the GPL-3.0 license. Before playing, you must create a game cache; afterward, some files used to create that cache can be removed from the ZIP archive. The project describes modified builds compatible with HBL and identifies those versions as based on emulator releases 2.2.1 and 2.3.1. Version 2.2.0 added ROM sets supported through MAME 0.119 and bootleg sets supported by MAME Plus!. Build options include save and load states, AdHoc multiplayer, a command list, Japanese UI, and 32-bit UI drawing. AdHoc requires KERNEL_MODE, and the readme recommends disabling 32-bit drawing outside NCDZPSP to reduce memory use. PSP-2000 expanded memory is available when compiled with PSP_SLIM, while a cache remains required. The listed build environment is Cygwin with PSPSDK revision 2318.
NeoDS
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.
