MegaDrive controller Modification for ZX-Uno

Mensaje por firepower » 13 May 2021, 17:06

To modify MegaDrive controller (cheap chinese clone with glob chip) you need to wire pin 7 to pin 5 inside controller (red circle)
and wire A and B buttons together for Fire 1 (or you can just use only B button for Fire1) (orange circle)
C button is Fire 2
