This game had quite a bit of depth to it...unlike Punch Out, this game wasn't about knowing the opponent's scripted moves and using the right timing/combinations to counter them. It was as close as the 80s arcade games came to Tekken or the like. Three dimensional movement, and the fighting was not as predictable or canned.
I don't recall if there was a console version of this game, but I seriously doubt it would have come anywhere close to the quarter-eater. It did become insanely difficult after defeating the second or third opponent, though.
Only other strike against this game was the between-round animation. Anyone who remembers it knows it was a very thinly-veiled sexual reference.
