Hmm, what's so problematic in getting PSX Games to work with EPSXE?
Here's how I do it...
1. Make an Image of the desired Game (via CloneCD for example)
2. Mount Image into Alcohol OR Daemon Toolz (let's say the Virtual Drive is called 'E:')
3. Open EPSXE -> Configure CD-Rom Plugin (must be one of Pete's)
Config:
4. Instead of your real CD-Drive you choose the virtual one generated by Daemon Toolz or Alcohol (in this case 'E:')
5. In point 2 we already mounted the Image, so what we do now is detect the read mode, async reads, max read speed etc. etc.
6. IMPORTANT: In Pete's Plugins there is the option to 'use PPF-Patch file'!
If you already have downloaded a PPF for the wanted game, just select it there!
Hit OK.
Finished! You can now play your game via 'File -> Run CD-rom' instead of 'Run ISO'
And you don't have to patch the ISO, you only have to select the Patch File in the Plugin

If you don't find any Patch files, you could try the German PPF patch... Grab it here:
