Yeah, the battery would be the first thing to look at.

You'll want to pop open the cartridge and check it with a multi-meter to make sure it's still giving an acceptable voltage. If it's toast, you'll have to replace it with a new one. Depending on how they've got it in there, it might be really easy, or it could require soldering or creative use of a knife and electrical tape (ala the 3-in-1 replacement).

Of course, if you want to save yourself the trouble I'd simply say buy a new one, but I can't seem to find a store that has stock on a lone M3 Real GBA Expansion pack. Perhaps try a 3-in-1?

I have an alternative problem: Whenever I plug-in my µSD to my computer, add/delete some files and replug it to my M3 DS Real and start Golden Sun for instance, I find out that I have an older save generally I lose 3-4 hours of game and it starts to get really annoying

How can I solve that ? And thanks in advance !

manually backup your save after your done, The M3 has no auto backup feature of save data for GBA.
