NeoCD/PS2
What NeoCD/PS2 is
NeoCD/PS2 is a free, open-source NeoGeo CD emulator for the Sony PlayStation 2. It adapts NeoCD/SDL to PS2-native libraries through PS2SDK. Games load directly from CD-ROM, with PAL/NTSC auto-detection and selection for video. 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 archive support is limited to the BIOS, and the emulator does not include the NeoGeo CD BIOS; users must find it or dump it from their own system. The releases page lists version 0.6c, including CDDA fixes and an auto-loop feature. Known issues include sound problems when frame rate is not full, timing problems, graphics glitches in some games, and the need to reset the PS2 to exit the BIOS. The project is distributed under the GNU General Public License and says it is used at the user's own risk.
