Spy vs Spy: The Island Caper Cheats For NES

1. Sound Test

   Right before a level ends (regardless if you win or lose), before the results box appears, press and hold the A & B buttons on the 1st controller. If done right, instead of the results box, you'll get the sound test.

3. Freeze The Computer

   While playing versus the computer. On controller 2, hold A & B and yell at the Famicom's 2nd controller microphone. If done right, the computer will freeze for a few seconds. If you freeze the opponent on top of a hazard, all his energy will be depleted!
