Firstly, I've read the FAQ files, and also the previous threads regarding this, but I still couldn't figure it out from the suggestions there.
The problem is basically the .sav files aren't being created. I already set the no$gba NDS backup thing to Flash-512kbps, exit properly, etc. If there's anything I'm missing, please let me know.
Also, even though the .sav file is not there, I can still play the game, save and load the save. I'm just not sure where is it coming from exactly.
I'm also using Vista if that makes any difference.
