I've recently purchased a 3in1 so I could play GBA games, Mother 3 specifically, but I'm having some problems. My Cyclo has the latest firmware so I don't think that is the issue. I copied the .sav file from my computer since I was playing it on VBA before I got the 3in1. The .sav worked fine and I continued playing from where I left off. The first save point I got to I saved and restarted my DS to make sure it saved correctly. I did this a few times because I've heard about GBA games not saving properly. Anyway, it worked and I continued playing. The next save point, however, I did the same thing but when I booted the game up again to make sure it saved it said "data corrupt" and now I have to start over. Does anyone else have this problem? And what could be causing it? Very frustrating as sometimes it seems to save fine but other times the data gets corrupted!
