Project 64 and Sony Vegas. Look 'em up, you should find download links for both (a trial version DL for the latter). A screen recorder and SM64 ROM would also be useful.

PJ64 is the emulator for the N64 games. That's how you would record gameplay from your computer, as well as use cheats like moonjump and color codes. You need the SM64 ROM to play the game, and the screen recorder to record video of what you're actually doing.

Sony Vegas is a video-editing program. You take all the video clips you recorded of SM64, and paste them into the timeline however you want. There you can add text, pictures, and effects, and save the video as a filetype uploadable to YouTube when you're done.

(The above coming from someone who has never used either software package. :P)
