Pause the game and type "ULRDABBA" for full weaponry (this only works once, if you type it again you'll lose a life).
On the title screen type one of the following:
STAGE 2 - "MISSHONEYBEE"
STAGE 3 - "DEPUTYOFLOVE"
STAGE 4 - "HASTALAVISTA"
STAGE 5 - "SNEAKPREVIEW"
FINALE --- "SHOWCREDITS"
Hit return after you type "SHOWCREDITS".
When you press 'HELP' and 'DEL' at the same time the on-screen action will slow down approximately 50%.
