Hacking Read/Write saves from GBA carts

[schweizter]

Hello, I have an R4 (and an M3) and I would like a program that can read and write saves from GBA carts.
I have eepinator, but that only does SRAM.
Is there a program that can do EEPROM and Flash?
Thanks!

If you have a slot 2 card then you can use the GBA Save Backup Utility to do this. It doesn't always want to kick through the first time though so try several times though before giving up. It will get stuck when trying to bring up a file list. At least it does on my M3 Perfect Lite.

This does any SRAM, EEPROM, or FLASH save type out there for gba carts. This is a gba rom in itself so you need a slot 2 cart to do this with.

Note that this is how I discovered the SharkPort Save file format and can now do manual extraction of the battery file contained in the files.
