I remember a long time ago, sometime in the 90's, I played a Final Fight arcade that had an end boss that was different from all the Final Fight games I've looked up (I looked up every one). The boss was kinda tall, like Andore, and after beating him, money fell from the ceiling. Also, sometime before the end boss, you were surrounded by a crowd of people cheering, like on the other games, however, people actual came out of the crowd and attacked you. Does anyone know which version of Final Fight this is? :|
I don't know about different versions of Final Fight, but falling money and surrounding crowd sounds very much like Pitfighter.
