Get more than 99 lives for Crash Bandicoot 2: Cortex Strikes Back

To make this glitch work, get 99 lives and enter a level. Break a life box/get 100 wumpas, and when the Crash symbol goes to the upper part of the screen, and starts to move towards your remaining lives, press Start and return to the Warp Room. You'll have 100 lives. Repeat this to get more lives.
