The Venom/Roll glitch?

Can someone please explain how to perform the Venom/Roll glitch in MVC where Roll constantly turns into Hyper Roll? I still haven’t figured that one out. :frowning:

EDIT: And while I’m at it, how do you perform the glitch where you freeze your opponent in a fierce Web Throw in MVC2?

Hel-LO! I’m sure you lot know what I’m talking about at least. You’ve seen those glitches before on combo videos. With all the advice offered here, I’d be surprised if you didn’t know how to perform these two glitches.
