Anyone looking for any means to save their game can use VMware's snapshop feature. It would require you to play the game inside of it, but it's fairly seemless once you do. It's great for practice or even for casual playthroughs.

I don't think it should be allowed in speedruns, however, as it's the equivalent of save states.

...

Well, now that I think about it, as long as it's used in the same fashion as the regular saves are, I don't see it being a problem. It's not optimal to use them and they consume a LOT more time than regular saves do; so it's not giving anyone an advantage. The only problem that arises is game time, which still needs to be discussed for the series as a whole.

They'd still be banned for ILs.
