You will need an extended SM64 ROM (don't ask me where to get it, I will not answer). You'll also need Toad'sTool 64, and you'll have to find out how to unlock Luigi using it. (again, you're on your own on that).
Challenge 1: Get to where I did with the Koopa Shell in Snowman's Land
Challenge 2: Get 8 Red Coins in Tick Tock Clock under one of the following conditions:
Easy: while the clock is moving at regular speed
Medium: while the clock is moving at double speed
Hard: while the clock is screwed up and everything moves randomly.
If anyone can accomplish Challenge 2, I wanna see it! record it and turn it into a video response! I especially wanna see the hard level beat, so if anyone can accomplish this, please show me, because I keep dying!
*EDIT* snappleboy16 has created a patch for Super Mario 64 with improved Weegee Textures. Apparently, people actually enjoy half the stuff I make, so you can download the patch here:

I'll have to ask him how to apply it though, but I'll edit this description when I find out. Thank you snappleboy16!
