They were several Bootleg versions of Street Fighter 2. I played one of them as a teenager and called it erroneously "Rainbow Edition". (
post here).
Funny thing though, a few days later I did my research and noticed that the "Rainbow Edition" wasn't really the one available in my neighbourhood. You see shotokans in Rainbow Ed throw one fireball at a time.
Whereas in my my version they launched 2 fireballs at the time. This is the version you can see in Mr.Q Fight Forever vid above at "0:55sec"; in the module it's seems a Super though.
I believe the version with 2 fireballs is actually called
Street Fighter II Champion Edition M5:
