What NeoCD-Wii is
NeoCD-Wii is a free, open-source emulator for Nintendo Wii that runs Neo-Geo CD games. It is a port of the NEO-CD REDUX GameCube emulator. Installation involves extracting the program archive to an SD card or USB drive, then placing game files in folders on that storage. The emulator requires a NeoGeo CD/Z BIOS file named NeoCD.bin in a BIOS folder at the SD card root. USB 2 support requires IOS 202. Game audio tracks go in each game's MP3 subdirectory and must use the Trackxx.mp3 naming pattern; 44.1 or 48 kHz and 128 kbps or better are recommended. Version 0.5 includes interlaced and progressive video modes, a filter toggle, configurable Wiimote and Classic Controller buttons, saved settings, and page-based game browsing. It supports the Wii's internal SD slot and is libfat compatible. The version history warns that some games may still show black screens or graphics bugs, and DVD support was untested. The project is licensed under GPL-3.0 and is available through GitHub; WiiBrew also links to the Open Shop Channel.
