Okay, firstly, on slot 2, it's NOT quality of the SD card. It freezes on my M3 Lite Perfect during this scene with latest fw and manager. I have a Kingston 2gb Japan, and don't see any other problems with any other games.
Secondly, I also get this problem on, guess what, my g6 lite. That's internal memory. It freezes at the SAME spot. And my G6 Lite is latest fw and manager as well. It's a problem with M3/G6 (for slot 2) software. Not your microsd card in this case, since one (g6 lite) has NO card at all, and it's all internal.
