I want to play on the old version of SR with the Raph stunlock but I'm not sure how. I also want to know if online multiplayer is possible on Legacy. Can anyone help with this?

A new update released for Shredder's Revenge that detailed some new fixes. Most of them are minor fixes but something they didn't mention is the fix on the Raph stunlock. I wonder what speedrunning will be like from here.

Should there be IL runs and would there be subcategories for each level? This is something I have had this on my mind for a while, and I would like to see other thoughts on the subject.
