Let's say you're playing the first Wario Land game and you decide to pause the action for a second to check out your stats.

Then, instead of hitting Start to get back to the action, you instead decided to hit Select 16 times. Then you might notice a little reticle appear around some of the digits.

If you hold down the B button, you can move that reticle around and change any of the numbers in the top row, altering how many coins, hearts, lives, and seconds you have on the timer.

And you can do this as often as you like to give yourself an advantage. So go nuts!
