I have a red Gamebox 400 in 1 brandnew and installed from a local arcade down here. It works perfect but I cannot get into the game menus to change difficulty and blood on/off etc. There is a System Service, Game Service, Reset and Menu button on the board. Only the menu button seems to work and it takes me to the 400 titles screen. Anyone have any idea if and how i can change the game settings? PLZ HELP!!
