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.
