When PCSX2 loads the game, the console page should have something like 'SLUS- XXXXX' and 'CRC=0x XXXXXXXX buried inside of all of that startup text, (where the X's are replaced by letters and numbers.) Check my attached screenshot - Notice how the console's blue text says 'Game CRC = 0圎8FCF8EC' in the middle of the fourth line? That's the CRC for the game I booted up. Which version of the game are you playing? US? UK? JPN? I ask, because each version has a different game identifier that the PNACH file needs. PNACH files are super easy to use once you learn how - Very similar to GameShark or Action Replay codes. I would urge you to go here and look for a file that uses your disc version and try it out Well seeing as kingdom hearts 2 is a ps2 game that can be played on pcsx2.you would be better off with a pnach file instead.
