I'm certainly not an expert in this matter, but still. This cartridge is pretty complicated. I think it will be hard to dump it and make it work properly on emulator. Maybe "dumper device" even would dump this cart that easy. I read that "dumper device" how to send proper signals to the mapper to switch memory banks correctly. So maybe you how to guess at your own how to make mapper switch memory banks properly to dump this cart. Maybe after all you how to write your own iNES mapper to make it work on emulator. I'm definitely recommend to send this cart to the specialist
