I want to backup saves from my retail games. I tried using NDS Backup Tool Wifi, but that couldn't read any of my games. I also tried SavSender/SavReceive, and it seemed to work, it says "Detected EEPROM of type 0, size 8192" and then sends OK - but all the saves downloaded were just empty files (all "null" characers). Are any issues with homebrew apps and reading save states on the DSi? Any suggestions to how to get it working? Using DSi, Acekard 2i.
