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?

I think new categories is something that is bound to happen, but one problem is that there is already a legacy category for older runs and it wouldn't make sense to merge what used to be current patch into legacy. One way I could see it done is keep legacy like it is and make current Any% pre-DLC/post custom game.

I have tried going through all the bosses that the glitch previously worked on, and I was able to land it on Bebop, Rocksteady, Groundchuck and Dirtbag, Rocksteady on level 7, (You could probably land it on Bebop in level 7.) Leatherhead, and Captain Zorax. I can't find a way to land the glitch on Rat King, and I softlocked on Metalhead a few times so there is a chance it's possible on him. Edit: It is possible to land it on Metalhead. It just takes a little bit of luck. Edit 2: It is also possible to land the glitch on Rat King by dive attacking the boss, backflipping through his attack after he gets up, and then using the backflip super. Edit 3: The stunlock got patched again.

Another thing I found was that in this update Super Shredder was made much faster. How much time it saves is something I don't know but I'm sure it'll speed up runs by a bit.

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.
