or it could be the microsd card. im using an Adata 2GB microsd and an m3 simply ds. sometimes it freezes and when i use moonshell to play music, there are sporatic split second freezes when it plays. videos are fine weirdly. no other homebrew on it. ive reformatted it twice and actually the music freezing is new this time. what could it be?
with my m3 whenever i tried to access games it would freeze, this was because i was using some cheap garbage microsd stick, so maybe try getting a name brand like kingston. i got a kingston 1gb for 20$ cdn =D and the problem was solved and no problems so far.
