*The above Dip Switches, are not only the FACTORY DEFAULT settings, but are also the correct Twin Galaxies Tournament Settings for this title.

SPECIAL NOTE: This track allows the use of bugs/glitches that are present in the hardware's unmodified game ROM under normal machine operation conditions.

Specifically allowed is the "bridge out" technique where it is possible to get the game into a state where the difficulty no longer increases and you no longer see torpedo boats or enforcers. The bug can be triggered by "jumping" a broken bridge by getting out of a weapons van and riding on the right over the broken bridge when an enforcer is on the bridge or nearby.

*Specifically not allowed are external physical modifications to the arcade hardware PCB or ROM that produce bugs/glitches in the gameplay.
