- Player 2 AWLAYS uses 2nd set of inputs regardless of "Cabinet" Dip Switch.
- Player 2 ALWAYS uses 2nd set of inputs regardless of "Cabinet" Dip Switch.
- Continue Play is always possible provided that you insert a coin when the
message is displayed on the screen (there is a 6 "seconds" timer to do so).
- Setting BOTH DSW bits 2 and 3 to ON gives you infinite credits and lives.
