Clear all twenty songs in both basic and trick modes
and save the game to a memory card. Note: It is best if you have auto
save enabled, as the game save your stages as you go along. When you
finish all songs, start the game again (after you are sure those forty
stages are saved). To be sure, check the records -- if you have a letter
for all of the songs then you have done it correctly. When you choose
the difficulty a "Push Down Twice For Maniac Mode" message will appear
when you have the red stars. If you want maniac mode for double, do
exactly the same as for single player.
