Fully Compatible

PSX4GP2X is the first PSX emulator for the GP2X. GP2PSX has a file menu for choosing games, HLE, save states, sound support and full controls. Compatability is high, with the speed games run at increasing with each release.

Major progress was made in December 2007. New test releases are now available. Discussion of the new version is going on at this thread on the GP32x forums. Many games now run much closer to full speed.


How to use PSX4GP2X

What you'll need:

  1. Games - Games will need to be ripped in a raw image format (.iso, .bin/.cue, or .img format with Alcohol 120% or CloneCD). PSX4GP2X is also able to load .bin's that have been compressed by PocketISO 2.0 into either .Z or .ZNX format.
  2. BIOS - You will need your scph1001.bin PSX BIOS (other versions renamed to schp1001.bin should also work)to run GP2PSX currently *UNLESS* HLE emulation is used (read below).
  3. Memory cards - For saving games. These come included with this emu.
  4. Put all these files in a folder on your SD card. The BIOS and memory cards (.mcr files) must be in the same directory as the emu. The games can be anywhere.
  5. After running, use the X button to select the game. Hold down either L or R while pressing X to enable HLE emulation for possibly better compatibility and speed.
  6. Raise and lower PSX CLOCK and PSX CYCLE to achieve a better frame rate. Settings PSX CYCLE to 1.1 and PSX CLOCK to 25% is a good start. PSX CLOCK at 20% and PSX Cycle at 4 or 6 also works well.

Solution: Your iso must be ripped to a raw image format. Other people have recommended ripping with MagicISO, but that doesn't work all the time. Try ripping with Alcohol 120% or CloneCD to a .bin/.cue, .iso, or .img/.ccd/.sub format.
