I have seen multiple Twitch Streams and Charity Marathons for running multiple rom hacks for Mario 64. Some are major, like Star Road, Last Impact, and Green Stars. Some are really minor, like SMB1-1, SM Run 64, and maybe Goomba's Easter Egg Hunt. There is a fairly large community, more than a lot of other multiple pages on the site. So how would I go about making this page?

i'd say, you better ask over here https://www.speedrun.com/sm64romhacks/forum :)
