I want to build a dev cart to test roms.
My first idea is to mod a original cart, take out ROM, solder 2, 8 bits flash ROM for 8Mbit (4+4).
This requires lots of wires and soldering work.
Do you find a better (easier) solution?
Another way would be a PCB conected to expansion port. Wire address bus (up to 256Kb, I know), data bus, and /ROM and /AS signals I think. While not cart in the connector, I suppose it shoul load the expansion port ROM at $000000
Thank you.
