I'm running CFW 6.60 PROMOD-C on a slim PSP 3001 and every Yu-Gi-Oh! Tag Force ISO I downloaded(Yu-Gi-Oh! GX Tag Force 1 and 2, Yu-Gi-Oh! 5D's Tag Force 4 and 5) will play normally for everything except a duel. Story Mode or Free Duel Mode when I try to duel someone the game freezes up. The only Tag Force ISO that works perfectly is Yu-Gi-Oh! GX Tag Force 3(Europe) and I have no problems playing it. If anyone can help me it would be appreciated.
