I'm fairly new to reproductions I've managed to make a few for SNES and a few for NES just so I can play games I don't own on a cartridge I use the kazzo inl device and it works great I assume there's got to be a way to use it for multicart Creations whether it's a particular program or just the way to bundle ROMs and then use the flashing program I use already. if somebody can help me that would be awesome I think anyone will responds ahead of time
