Can't help but notice that basically every run has been on PS1. Is it the superior version, or just most accessible? If the other releases are different, then are they different enough that there would be strat deviation?

The current rules for this game say to start timing when you select new game and end after credits say "end." However, the time of Cacodemon's run as listed would therefore be over an hour (about 1:00:08 by my best effort). Instead the listed time is 55:48, which I can't understand - by every timing method I know of, I couldn't come up with that time. My best guess is that it was retimed with SDA rules (start at new game, end at final hit on Geist) but was then mistyped. That's just because I tried timing with those rules on my own and got 54:48, exactly one minute less than the listed time, and 6 seconds slower than Cacodemon's own timing method which was SDA rules but starting from first cutscene.

So - if I'm missing something I'm happy to be corrected, otherwise it seems to me that both Cacodemon's time on here and the rules should be amended to match modern timing conventions.

I've been searching for a new speedgame recently and this one is looking sick, so I'll probably give the Allen run a shot regardless. That said, having the extra 2 player category would make learning the game that much sweeter. So somebody please school me on this game - would co-op runs be any faster, or would it just be a single player run with extra baggage? Has anybody ever attempted it before and if so are there any recordings?

So I'm returning to this game after some years and relearning Richter all bosses atm, but there's one specific movement which I can't replicate while watching through the current wr. In the last room of alchemy lab, he slides off a ledge and whips while falling, sending him fast enough horizontally to hit the wall before air slashing. The same movement is used at a couple other points as well, like Olrox's room. When I do the same, I don't get nearly the same distance. Is there a hidden input in there? Something else I haven't learned about momentum?
