NeoCD/PS2
What it is
NeoCD/PS2 is a free, open-source NeoGeo CD emulator for the Sony PlayStation 2. It adapts NeoCD/SDL to use PS2 native libraries through PS2SDK, and loads games directly from the CD-ROM. Video can detect PAL or NTSC automatically, or users can select a mode from the in-game menu; that menu also provides filtering, fullscreen video, and frameskip controls. The emulator supports two controllers, stereo sound emulation, CDDA playback, and NeoGeo CD memory card support that uses 45 KB on a PS2 memory card. ZIP support is limited to the BIOS, and the NeoGeo CD BIOS is not included, so users need to find it or dump it from their own system. The project is distributed under GNU General Public License version 2 and says it should only be used with games the user legally owns. Its release listing includes version 0.6c, with CDDA fixes including an auto-loop feature. Listed issues include sound problems when frame rate is not full, timing issues, graphics glitches in some games, and having to reset the PS2 to exit the BIOS.
For and against
For
- Loads games directly from CD-ROM
- Supports two controllers
- Includes stereo sound and CDDA support
- Offers PAL/NTSC detection and selection
Against
- NeoGeo CD BIOS is not included
- ZIP support is limited to the BIOS

The verdict
NeoCD/PS2 provides NeoGeo CD emulation specifically for the PlayStation 2, with direct disc loading and controller support. Users should account for the missing BIOS and the listed sound, timing, and graphics issues.
Who it suits
NeoCD/PS2 may suit PlayStation 2 owners who legally own NeoGeo CD games and can provide the required BIOS. It is not suited to users seeking a general-purpose emulator across platforms.
