The dip switch settings for Bombjack Twin shown below are automatically parsed from Multiple Arcade Machine Emulator (www.mame.net) C source code, so some of the settings can be incorrect. However, if you notice that some settings are constantly incorrectly displayed in more than one game, please contact me so that I can fix the problem. Happy gaming!

If you are trying to change this game's language or region, you might have to replace/reprogram some of the game's ROM chips.
