I'm about to transfer all the games from one cart to the R4 for my girlfriend to use. She mentioned that when she was playing Alvin & The Chipmunks on the G6 Real, that the game would freeze from time to time for her. I think I remember trimming the game when I put it on the cart. So maybe that is what is causing the problem. I know this game isn't the most popular. But to anyone that has played this game on the R4, did you ever experience any freezing? I'm going to put a new clean download of this game, untrimmed, on the R4 just to be safe. But I was just wondering if anyone else has ever experienced any freezing on the R4 with this game. Thank you for any info.
