How ironic that even Mike Tyson can't beat Mike Tyson.
Sigh. Finally beating that game was one of the proudest moments of my gaming life. Think I was 11 when I finally did it. Felt great, wasn't sure if it was a fluke. Pulled it off again two years later in a room full of my friends when we were taking a break from recording their album. None of them had ever done it and couldn't believe I pulled it off. For a few minutes, I was a God.
For the record, I've only ever beaten Tyson by playing the game from the beginning. I've NEVER been able to beat it using the cheat code and skipping right to him. I actually need to "warm up" by going through the whole roster first; if I go in cold against Tyson my timing is off and I get murdered.
