I've found that if you byte swap the save file for Majora's Mask, it'll work just fine in Mupen64Plus. I don't know Python, so I can't fix it, but hopefully someone else can.

vcromclaim already byte-swaps N64 SRAM save data. Its problem here is that it doesn't recognize the size of the save file as an appropriate size for an SRAM save, so it bails.
