Rockin' Kats isn't really that tough of a game, especially when you can refill your HP any time you want. But, you still have to play through the game to see the ending, which could take a while.

Which is great if you're borrowing the game and don't quite make it to the end before you have to take it back.

Rockin' Kats isn't really that tough, but it does have its moments that are slightly frustrating.

Then hold Down on the control pad + A + B, and while holding those, press Start to unpause. Done right, you'll be rewarded

With six lives and a full life meter!

I was able to do this a half-dozen times in the course of the stage, so you can go nuts doing it as often as you like.

Just be aware that if you have more than six lives, they'll roll back to six when you do this trick.

But odds are that won't bother you too much.
