This game is super fun!! I was wondering through, I'm seeing an issue where the game seemingly can't read an existing save file. Have you seen this issue? I wonder if it has anything to do with the MBC settings, it looks like Plus is MBC3 while the original is MBC5.
Also, I was wondering if you might be interested in having a supplier for game cartridges? I make my own, just for fun as a hobby, and I'm looking for GB home-brew developers that might be interested in buying from me!
