What it is
NeoCD-Wii is a free, open-source Nintendo Wii emulator for Neo-Geo CD games and a port of the NEO-CD REDUX GameCube emulator. Installation involves extracting the archive to an SD card or USB drive and placing game files in folders there. USB 2 support requires IOS 202. The emulator also needs a NeoGeo CD/Z BIOS named NeoCD.bin in a BIOS folder at the SD card root. Game audio belongs in each title’s MP3 directory as Trackxx.mp3 files; 44.1 or 48 kHz and 128 kbps or better are recommended. Version 0.5 lists interlaced and progressive video modes, a filter toggle, configurable Wiimote and Classic Controller buttons, saved settings, and page-based browsing. The project supports the internal SD slot and is libfat compatible. Some games may still show black screens or graphics bugs, and DVD support was untested. The repository lists GPL-3.0 licensing.
