Of course things always become more mysterious when you add Proto Man in the mix. It's entirely unknown what this scene would have been used for, and it sort of implies Mega Man died or something? It's true soccer is pretty rough in some countries... Incidentally, these scenes are available only through hacking. For the 17 years the game has been out, there has never been a legitimate way to access these. You can read up on even more unused contents at The Cutting Room Floor.
