What was the Neo Geo CD?

The Neo Geo CD was a follow up to the Neo Geo which was released in order to keep manufacturing costs down. The Neo-Geo was a cartridge-based arcade and home video game system released in 1991 by Japanese game company SNK. The system was years ahead of other home systems of its time, offering huge, colorful 2D graphics, and high-quality sound.


  1. Download the SDL-libs and install them
  2. Download the latest version of NeoCD and unzip on your SD-Card.
  3. Acquire a Neo-Geo CD-image.
  4. Open the CD-image and copy the contents back into the directory that the CD-image is residing in.
  5. Delete the CD-image file.
  6. You should be able to remove any MP3-files to save space since the emulator doesn't yet support sound.
  7. Select all the contents of the folder and copy them to the SD-Card, preferably in a subdir called roms. You can zip the files if you wish for easier handling.
  8. Run 'neocdgp2x' under Games on your GP2X and choose the game you want to play.

Emulator Versions

2005.12.03 neocdgp2x.gpe 6690451f1d806d9830b2f6bc31fcbec8
Not really sure what changed here, but it is different.
2005.12.02 neocdgp2x.gpe 9408ef18cd43501ecdb5d4b80d0991fa
Exit bug fixed. Button mapping changed to match NeoGeo CD Control Pad.
2005.12.01 neocdgp2x.gpe 3d3ffcc964dc48c9141d9ba0ec027db8
Improved compatibility and slightly better speed. Layering problem has largely been resolved. No sound yet. May require a skins0 directory and files to function correctly. Includes two rendering modes selected by executing the rom with either the A or B button. "B" is the new renderer. Also includes support for MP3 music in games, make a neocd.mp3 folder and copy the mp3s into it inside your rom folder.
2005.11.30 neocdgp2x.gpe afc3b75a10b7988281972240f53c20df
Improved speed and compatibility, due to corrected Z80 emulation. It seems that there may be a layering problem that remains and affects playability of certain games that "cheat" on parallaxing. (Sadly, seems to be most fighting games).
2005.11.27 neocdgp2x.gpe bd9a502bace0ebf0d091ac749934bb9b
File browser, improved speed and compatibility.
