Tip: With one of the Konami Game Master cartridges in slot1 and the game in slot2 you can use the Game Master to start at a higher level and/or with more lives.

Alternatively with the game in slot1 and Twin Bee in slot2: Your ship is a twinbee and energy pods are bells.

Holding the powerup key/button during the intro demo gameplay causes Vic Viper to power up SPEEDUP every time it picks up a capsule. Releasing then pushing it ends the demo though.
