I don't mean to be rude, but you seem like you might be a little fixated on this.
Is there some reason beyond just having enjoyed the game that gets you so worked up into a lather over it? There are so many fighting games you could play. Street Fighter 2: Champion Edition, Samurai Shodown, Tekken 3, the aforementioned Smash Brothers, heck, you could play the vs. mode in Double Dragon on the NES (Dash away from enemy, enemy chases, move downward, enemy passes, move upward, quickly dash and punch, repeat) just for old times' sake.
What makes this one game so indispensable to you?
