I noticed that Practice, Beginner, and Advanced modes all have score tracks, and have also noticed that for M.A.M.E. there are tracks posted for all four difficulties. I propose adding a track for Insane in the arcade section for the game, following the same rules (1 player, 3 lives, no continues) as the other three difficulties.
P.S. I also plan on attempting setting a record if this track proposal is accepted.
