Street Fighter 2 Beta for the Super Nintendo 

This game is interesting. It is a hacked version of SF2 just like the Champion Edition Hack that was released a bit before the original SF2 Turbo on SNES. It shows all characters on the select screen, but I coudnt select any of them... I guess this version is somewhere in between the original and the Champion Edition, and has also, Rainbow Edition M7 as heavy inspiration.
