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.
NeoCD/SDLx Unleashed
NeoCD/SDLx Unleashed is a free Neo Geo CD emulator for the original Xbox. It runs many original Neo Geo CD games and reads real discs in ISO9660 format.

It supports one or two players, full CDDA audio, region selection and memory cards. Display modes include 480p and 720p, selected according to dashboard settings. Video filters are AdvanceMame2x, Simple2x, SuperSai2x, SuperEagle and Scanline. Source code is released, and the download is a 448.6 KB ZIP attachment with no Digiex registration required. The page reports miscellaneous sound and timing issues and provides the program without warranty. The listed platform is the original Xbox. AES and MVS emulation, plus other related SNK arcade systems, are not supported.
