I might be alone on this but I think the best option would be to turn off or remove the RAM board and physically connect and use the hardware in the cartridge. Maybe there's already a core or branch of a core available now that is expecting a cartridge be connected to the mister IO rather than the RAM board?

I've been curious about this as well. Wouldn't there be enough IO if we had a special ram board that could be bypassed or simply powered off and run all that freed up IO to a cartridge reader PCB? I would think there would be enough IO for every cart except for the Neo Geo.
