I have a problem running this game with my laptop. I'm quite sure that my specs are more than enough to run it. May I know your exact settings? The JPCSP version I used is the r1980 one.
for setting go to Options=>Configuration
*tab General set your UMD path Folder(ISO/CSO) & TMP path folder.
*tab Region you can change as you like.
*tab Video & Audio default/don't check anything/none.
*tab Memory default
*tab Media Enable
-Use Media Engine.
-Decode audio files with SonicStage.
-Use non-native fonts from flash0 folder(for this you can enable/disable up to u).
*tab Compiler default or you can change Maximum method size value to 500.
*tab Crypto default
note: for SonicStage you must install this software(SonicStage) first, then you can use Decode audio files with SonicStage.
