so I have an r4 ds with a 3 in 1 ezv expansion pack for slot 2. I am also using 3in1_ExpPack_Tool aka Rudolphs Tool... but I can't seem to figure out how to get saves to work. Super Mario Advance 4 says the save file is corrupted and everything else just won't save any data when I tell it too... I have save folder in the GBA directory like it says but it isn't saving anything... anyone know what I am doing wrong?
