Fester's Quest Cheats For NES

  1. Beat Bosses Instantly

    You must have a key to do this trick. Once you reach a boss, press start and select the key. From the middle of the screen, walk left and down and rapidly press 'A'. It will say ''Thing gives you Invisible Potion. Press start and you'll be at a scrambled screen. Wait a moment and you'll be at the staircase for the next area. Just DO NOT do this on the final boss, or the game will freeze.

  2. No Sound

    Quickly press Select twice to pause and unpause the game, and the sound will be gone. To turn on the sound you have to run into a wall and then pause and unpause the game.

  3. Fourth Energy Bar

    To get a fourth energy bar, just before the last hot dog stand before the gravestone that takes you to the alien ship, there are bushes that you can walk through to get to the large building with the three single bushes in front of it. Use a key on the door, watch the cutscene, and you'll have a fourth energy bar to defeat the aliens with!
