So I was messing around with hack ROMs by having two Omega Rubys on the Gateway card. In the process I somehow managed to corrupt my original savegame. Now even with undo'ed changes to the ROM roster on the micro SD Card nothing has changed. I also injected an old "nand.bin" file to the SD Card but the savegame is still corrupted. I'm also still using the previous/unmodified ROM. How can I recover the data? Where is the savegame stored even? It's not the SD Card I guess.
