1313The "To Do" list:
1414-----------------
15-Consider moving the 3 cartridges of the slot 2 in a sowtware list since they are interchangable
15-Consider moving the 3 cartridges of the slot 2 in a sotwware list since they are interchangable
1616-Hook the z180 clone, the DSP 1A/1B and the Super FX
1717-Add the missing GROM4-1
1818-Add the possibly alternate revision of the attract ROM, with Kirby holding a coin
