While there is a fair bit of menu-ing needed during this speedrun, there's so much stuttering and waiting around that personally I'd rather use IGT. This also allows use of GDEmu and negates inaccurate emulator load times which I think is a positive thing allowing for more accessability. I personally have had to deal with 2 Dreamcast disc drives dying on me and currently use a GDEmu so I'm glad I can use IGT for timing rather than have to do manual Time without Loads.
