i've been playing street fighter II turbo on the SNES for quite a while... more specifically, i'd been playing the super famicom version and i don't believe i even once encountered the yellow or orange or red or whatever color hadoken. but i've recently got my hands on a copy of the US version and playing as ken against ryu have seen it more than a few times. what gives?
after a few minutes of google searching (with very few results) i've only read that it may be a glitch. i'm just curious as to what causes it. any romhackers here know why?
