This is a basic EEPROM backup tool, allows you to read and copy save data to and from DS gamecart EEPROM.
Basically all it does is copy from EEPROM to FAT, and copy from FAT to EEPROM. Super basic text UI.
It also supports using SRAM as storage, and if you have a gba cart in slot-2, and a flashcart in slot-1, you could copy the sram off the gba cart to flashcart.
Hexdump is not implemented yet.
May not work for slot-1 card users because inserting the slot-1 flashcart causes a reset.
