the new idea is to take a song from any numbered megaman game and alter the time signature so the new time has a number from the game of origin e.g. Songs from megaman 4 can be in 5/4, 3/4, etc., songs from 7 can be 7/8 or what have you, 6 can be in 6/6, 6/4, and so on.
originally the idea was for "megaman 3/4" which involved only megaman 3 and 4 songs and put them all in 3/4. But not enough expressed interest and a lot of megaman 4 songs I don't feel work well in 3/4 (specifically wily castle 1, which I think could sound great in 5/4).
