At the title screen, hold B and as soon as the first "P" letter of "MAPPYKIDS" (the 3rd letter ) blinks, press A. If done right, you'll start with 20 lives.

Hold on the second controller the A Button for 5-7 seconds, the B Button 3-4 seconds, and Select on the first controller for 4-5 seconds, then press Start on the first controller. Note that this cheat may take several tries to execute, as what you're doing is holding the buttons to raise internal counters that increment about 30 times per second to a specific range - if you fail, just reset the console and try again.
