I've got a save file that I'm desperate to get working on my MiSTer, but I'm having a really difficult time trying to figure out how to get it to work. The saves are for Shining Force III Scenario 2, and the emulator that wrote the file is OpenEmu on MacOS. It uses Mednafen as a backend, and it appears to be using the same save format; it's got a bunch of .bcr and .bkr files labeled 0-6 and C. I found two converters but they are buggy, have practically zero documentation, and I have no idea what I'm doing, especially because all of them expect to see a single file.
Anyone have any idea what to do with these?
