Alright, thanks.Weird. I guess I still have to tweak the FAT32Format code a bit (the program no longer calls the format.exe tool from Windows). I assume it didn't really fail to write the FAT partition sectors, though. Otherwise a different error message should have been displayed.
There should be no problems if you format the new partition using another program, but make sure it is FAT32.
Another question, is it possible to inject a sysNAND.bin into en emuNAND?
Like if I dumped sysNAND to a .bin file using EmuNAND9 or similar?
