Another way is to play the modified ROM on an emulator. See what game is loaded and what save is being shown. After all, maybe for a particular type of cart with a particular type of ROM, it’s possible that there more than one save. I mean, you evidently *could* reflash, but maybe the save is stored differently then expected.
For that game, what is the name of the save extracted using the program, and how many saves do you get? (I want to determine the hex address of the save and then ask you to use a hex editor to extract everything after that point; I don’t want any ROM data to be accidentally extracted and sent)
