Lots of time lost pre-Norfair and on Tourian farming, perhaps it can be close to a minute faster or so. With NGC port loading times between areas this would be a 27:01.191, from the first frame in Brinstar to Samus first frontal frame on Tourian exit elevator. Played on Nestopia using FDS BIOS. Avidemux times this as 29:28.934.
