Start is pressed on title screen at 2:48. Final hit on last boss at 1:54:00. Calculated run time: 1:51:12. (This submission is an invalidated "100%" run because I actually missed a stage, so I am submitting it as Any% to help get a leaderboard going for this game. I will submit a proper run when I can. Also, save states were created -- but NOT used -- during this marathon run.)
