Crash the game:
To crash the game go to either level 5 or 9 and get as many programs hacking the door codes as possible. It may be best to set the code to the one over the actual code (See above) so the program won't find the code too soon.
Level select:
Turn off your sound at title screen, now hold up and left on the joypad and keep tapping both A & B buttons until it says "LEVEL 1" instead of "NOW TELEPORING TO LEVEL 1".. Use joypad to choose level. (from Star*Lynx)
