Is there a way to keep the save files from +10 EEPROM YES games? Because I play one of them and it's everything perfect, but I play other game and, I assume, it overwrites the other game (Majora's Mask and Luigi's Mansion).
The problem is that whenever I change to Majora's Mask, the save is corrupted. I play enough to make a save file, reinsert to change game and when I come back the save is gone again if I play Luigi's Mansion, but the Luigi game keeps his save file and Zelda loses it. Even if I just cycle through the games and play Zelda again after saving, the data is corrupted.In my experience, it works fine (on newer writers and templates).
Just remember that it dumps the EEPROM when you change games with the button or auto-scroll. Do NOT change MicroSDs without changing games first, and you should be fine.
Definitely not working.You could patch all of the games after #10 to EEPROM NO. This method is outdated but may work for you.
