Control two players at once:
Note: This trick requires two Wavebird controllers. Set the receivers
on the same channel and use one Wavebird on the same channel. You can
then control two players at the same time. Set them side to side
(horizontal) or (vertical) above each other by pushing them to the
edges of your screen. If one gets wasted, you can quickly change color
so you will have one black and the other white.
Increase score permanently:
Every time you continue, the last digit of your score goes up by one
permanently. For example, if you continued once it is a "1", twice for
a "2", etc. This is useful for gauging how much you have continued once
the "Free Play" option has been unlocked.
