Notes

  • The reset line cut has not been tested. It could be either before or after the resistor. Please progress with caution. VA1 is almost identical to a Mega Drive 2 VA4 region mod, in which case the reset cut should be correct as it is confirmed working on a MD2 VA4. The Genesis 3 VA2 will need testing to confirm.
  • Genesis 3 VA2 controller point C9 can be done on the top side. The small resistor (R52) next to the EM components.
