Nintendo Puzzle Collection Cheats (GameCube)

On the options screen where you select the round, speed, and tune, put the tune to off,
the round to 10, and the speed to hi. Then go to the round selection option and hold up
and press Select. Rounds 11-99 will be unlocked without having to complete round 10-10.

NOTE: This will have to be input each time you transfer into the GBA, because it does not
save.

NOTE: This does not work with the Yoshi no Cookie on Nintendo Puzzle Collection, but once
you complete round 10-10 and unlock rounds 11-99, they stay unlocked.
