This hack makes it so that coins will kill you in SMB3. You get infinite lives, so dying isn't the end... but if you pick up a single coin, you will take hits until you die. To balance this out, you are able to keep a reserve powerup for switching during play. If you switch to a new powerup before you take the final hit, you -can- survive. This is a great hack to totally change the gameplay of SMB3.
