I have been messing about with different roms to try and get a better understanding of how it all works,i have done all the lamps,buttons etc,but when the machine reinitializes (sc4) the zero credits show for about one second then the alpha jumps to read meters? s door and c door both unticked, is there something i have stupidly missed here>?
any help will be appreciated,i'm sure someone else has been here before
