In T&C 2, you have to take a gorilla that's riding on a skateboard or surfboard across a bunch of levels. Problem is that he's unusually fragile, so you're going to see this a lot.

But don't despair!

You can simply go to the title screen and press this sequence of buttons:

Left, Up, Right, Up, Right, Down, A

Which will put unlimited lives at your disposal.

So now you can wipe out as often as you like!

And, trust me, you're going to be wiping out a lot.
