No longer the World Record. My new best time is 1:19:28 (http://www.twitch.tv/altabi...

This is a speedrun of Mario & Luigi Superstar Saga done 1 hour, 20 minutes, 12 seconds. I played this on the Wii U Virtual Console and used the Classic Controller Pro.
This run uses glitches and major skips to save over 2 hours over what a glitchless time would be. The Mush Badge is picked up to make up for the low level I am by the end of the game.
This run was really good. All tricks were done on first try, no extra encounters, good stats, really good attack patterns from Cackletta, and great execution overall. There's still a few seconds that can be saved from movement errors/optimization, but barring having a run with extremely high power to kill Cackletta in three turns there are not going to be any major time saves left under the current knowledge for this game.
