When it's ON, you have these features : * there is an extended "test mode" that also allows you to test the BG and Object ROMS via a menu. * You can end a level by pressing BUTTON3 from player 2 8) - The "Adult Mode" Dip Switch determines if "Shanghai Paradise" is available. - The "Quest Mode" Dip Switch determines if "Shanghai Quest" is available. - The "Use Mahjong Tiles" Dip Switch only has an
