I just checked on here lately, and I noticed it was changed a lot recently. I want to know what one of these new categories are and what they mean. It doesn't say in the rules.
So No SBA means just Any% and IGC means Cheat%, which I actually get very easily, but what does (Normal) SBA mean exactly?

SBA stands for Skee-ball abuse. Skee-ball abuse is an exploit which was found recently and is used to generate a lot of Shiny Objects in a short amount of time. This exploit changes the route and the way you play the game completely. That's why the categories are seperated.
Examples of the Skee-ball abuse can be found here:

Oh. Isn't that thing from Goo Lagoon, just wanted to make sure.

Yes.
