Hi there
this is the Best OpenBOR Fight Final I've ever seen!
I've been playing it these days and the first thing that came to my mind was: What about the Saturday Night Slam Master (SNES) characters?
They are much like the characters in the Street Fighter and Final Fight. It is virtually the same size (just do a comparison of the Haggar Saturday with the Final Fight). The only thing that differs greatly is the color (but this can be changed).
I think can use this site to take a look:

El Stingray is a very cool character, I would love to see him in the game
I mean, it is part of the same universe of Street Fight and Final Fight, so why not? ;D
The other thing I thought, was to add other versions of Guy and Haggar (Final Fight 2 and 3). I think it would nice to have those other versions to choose from.
