Up until recently, I have been happily using an M3 GBA Expansion Pack with my M3i Zero Sakura. Everything was working correctly such as saves and whatnot. One day I tried to play a gba game, and it just wouldn't load, as if the GEP wasn't inserted at all. I confirmed that it still says that a DS Option Pak is inserted, so I know it probably isn't faulty, and I have left it in to charge for several days, but it still fails to load games. DS games still work fine, so I know it isn't the card. I've read that it's possible it to stop working if the battery had completely died, but I'm not sure about that. I've tried loading games that I knew were at one point working, so I know it isn't the games themselves. I have the newest Sakura firmware; it could be possible that there's a bug in the new firmware causing this; could someone here confirm that their GEP is working with the newest firmware? Any help on this would be greatly appreciated. The help I've gotten from M3Adapter has been pretty useless. Thanks.
