What NeoCD-Wii is
NeoCD-Wii is a Nintendo Wii port of the NEO-CD REDUX GameCube emulator, designed to emulate Neo-Geo CD games. The project is free and open source under the GPL-3.0 license. Its installation instructions call for extracting the archive onto an SD card or USB drive, then placing game files in folders on that storage. USB 2 support requires IOS 202. The emulator also needs a NeoGeo CD/Z BIOS file named NeoCD.bin in a BIOS folder at the SD card root. Game audio tracks belong in each game's MP3 subdirectory and must be named Trackxx.mp3; 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. The version history notes that some games may still display black screens or graphics bugs. The port supports the internal SD slot and is libfat compatible; DVD support was untested. The latest listed release is version 0.5. The repository provides installation guidance, and the application is also available through the Open Shop Channel.
