I’ve read about/experienced quite a few repeatable incidences of unexpected behaviour but info is usually sketchy or scattered around the place. Maybe it’s a good idea to list this stuff somewhere. Know of a bug/glitch? List it here.
Zangief has a short jump ability
Abel has an infinite against Chun/Rufus
Akuma supposedly has an infinite with s.lp s.hk [edit: apparently it’s repeatable but not infinite]
Ryu can “teleport” through Boxer by FADC’ing a close standing roundhouse
Blanka can cancel from a rock crusher into a forward hop through every character except Guile (he lands on the same side)
Pressing Viper’s Taunt 1 repeatedly causes her to “hop” back a bit
Spaced just within range, there’s a slight probability that crouching forward or roundhouse will whiff against a standing opponent (any more info on this?)
Pressing 3 hits/kicks doesn’t always register as such. eg. lp followed quickly with 3p registers as lp followed by mp + fp. It doesn’t appear to have any effect on gameplay and I don’t know if this is exploitable
El Fuerte vs El Fuerte, there is some very strange properties doing his RSF into a slide, I think if you only do two hits and then a slide, or some reason you slide through him and just pop out on the other side. (Might be wrong on two hits, could be three or four but I think it’s two.)
As Bison against Akuma there’s some weird stuff with popping right through him periodically, I don’t know the circumstances but it definitely happens, it’s kind of like the Akuma-Sagat teleport glitch where if Akuma teleports and Sagat does a s.hk Akuma pops back out in front. There’s also a glitch if Akuma does an EX air fireball, gets hit by Bison’s ultra, and then the fireballs hit Bison, it does some weird stuff to Akuma (he basically gets hit by the ultra without a cutscene).
i’ve definitely seen the glitch where cr.rh goes through the opponents legs while i’m playing as balrog. seen it quite a few times. i always attributed it to latency issues since i’ve only seen it online.
It also depends on the opponent’s stance though. Some characters have dynamic hitboxes (eg. Dan), so I move might hit in one frame but miss in another, even if they haven’t moved. That said, I’ve tested this with Balrog as well and if you’re just within range the c.rk does sometimes whiff. Although, I’m not sure if it’s a case of the move hitting when it shouldn’t, or missing when it shouldn’t.
