Rainbow Islands Extra Cheats

In the option menu, choose number of lives and select ‘0’. Then you can start your game normally. When you died, instead of Game Over, you get a lot of extra lives like ??, ?! and other symbols in pair as your number of lives. However, it is not really unlimited. After you died a lot of times (about 400 times), your number of lives became 99, and when it reached 0, the game is over.
