In their own words
NeoCD/PS2
NeoCD/PS2 is a free, open-source NeoGeo CD emulator for the Sony PlayStation 2. It is a port of NeoCD/SDL, adapted to replace SDL components with PS2-native libraries using PS2SDK. Games load directly from the CD-ROM. Video offers PAL/NTSC auto-detection and selection, while the in-game menu includes filtering, fullscreen video, and frameskip controls. The emulator supports two controllers, stereo sound emulation, and CDDA playback. NeoGeo CD memory card support uses 45 KB on a PS2 memory card. ZIP support is limited to the BIOS, and the NeoGeo CD BIOS is not included; users must find it or dump it from their own system. The releases page lists version 0.6c with CDDA fixes, including an auto-loop feature. Listed issues include sound problems when the frame rate is below full speed, timing issues, graphics glitches in some games, and needing to reset the PS2 to exit the BIOS. The project is distributed under GNU General Public License version 2 and says use is at the user's own risk; the README says it should only be used with games the user legally owns.
NeoCDRX
NeoCDRX is a free homebrew emulator for Neo Geo CD and CDZ games on GameCube, Wii and Wii U through Virtual Wii. It supports region settings for USA, Europe and Japan, which provide different languages and can affect some game content. The listed processor cores are Z80 3.6 and M68000 3.3, and audio controls include a three-band equalizer for music and sound effects. Supported controllers include Wii Remote, Wii Remote Plus, Wii Remote with Nunchuk and GameCube controller. Media options include SD/SDHC, USB and DVD, plus GameCube options WKF and IDE-EXI V1. Virtual memory card saves can go to SD or USB, or to a physical GameCube memory card. Setup requires a Neo Geo CD/CDZ BIOS file named NeoCD.bin in NeoCDRX/bios. Each game goes in its own folder under NeoCDRX/games, with an mp3 subfolder for music. Wii and Wii U Virtual Wii installations are packaged for Homebrew Channel; using the Wii version requires a way to run unsigned code. The README describes the project as GPL open source, while GitHub lists LGPL-2.1.
