Yeah, right. I wish I had time for that.
Anyway, there are several OOT runs that I did a long time ago, one being a Dodongo's Cavern run that was about 10 minutes long. I haven't done any runs for that game since, but I know I can beat that record easily if I ever considered doing it again.
EDIT: Out of boredom, I did a run of Armored Armadillo's stage in Megaman X without any upgrades in 1:58, excluding the boss.
