Sonic The Hedgehog speed run [SMS] in [12:16]

This run is obsolete, as I have gotten a 12:07 run recently (and there is still room for improvement in it). My aim for this game is to get around 11:50. This an old run through Sonic The Hedgehog that I have since beaten. I managed to match my old personal best times in practically every stage. If it weren't for the fact that I came up with a new strategy for GH3, I would have already submitted this run to SDA.
