To begin with, I'll put in my own records, as well as those I know of from other people who aren't active anymore.
Shine Shine Galaxy
Sacred Grounds Any% Speedrun
Sacred Grounds Low% (Min. Items) Speedrun
Guxt Score Attack
Other categories I may add in the future include full-game Cave Story/Ikachan runs (if anyone actually bothers to do them), records from challenge mods and other things by Pixel that I forgot to put here. If you want to submit a score for something, I won't expect any proof (e.g. pic, vid, replay file etc.) unless it's extremely good and I don't know you very well, so post away!
