The lettering on Dee Jay's pant leg was originally "MANTIS". However, the "N" and the "S" were both reversed when he faced the other way, so it was changed to "MAXIMUM".
The "new challengers" characters introduced here are among the least popular characters in the Street Fighter universe, and as such, rarely appeared in future games. Cammy was the lone exception to this rule.
One of the boats in Ken's stage has the name "Buppo", and this was one of the game designers. This also applies to Super Street Fighter II Turbo (1994)
In the original screenshots of the SNES version, Cammy is seen to be wearing stockings. This was removed in final versions.
First game in which all of the male characters sounded different (Capcom used individual voice actor recordings for each one.)
