Pause game then type "DIPUTS". Pressing the number keys now lets you teleport around the level. When you load up disk one and the word {GOONIES} appears, hold down one of these mystical keys for various effects:
'F1'--Infinite energy and infinite weapons
'F2'-----------------------Infinite energy
'F3'------------------------Infinite lives
If this cheat should fail try typing this one in instead! While playing the game, hit the pause button and type in "DIPUTS". Now you should be able to press any number key to teleport to different stages throughout the current level.
