I was this video on youtube because cheese05 watched it on stream and it was a 120 star human theory TAS done on a Nintendo 64 and I wondered how he did it. I sent him an e-mail a while ago but havent got a reply so I came to the most helpful place to ask questions on speedrunning. Video Link:

you ¤really¤ should post this on the sm64 subforum, not on the general forum.

Actually, since they're asking about the TAS, and how they're made, you're better poking around TAS Videos and checking their forums out. http://tasvideos.org/

For the most part TASs are done with a combination of frame advancements, precise button input, and an in-depth knowledge of the game.

Thanks for help!
