Based on the manga localized in North America as Fighting Spirit, Hajime no Ippo - The Fighting! is a game where you fight your opponents in a similar perspective to Super Punch-Out!!. You gain more special moves as the game progresses.
In this run, errror1 earns those special moves and uses them to beat down his opponents as fast as possible. He also takes advantage of an interesting quirk in the opponents' AI, ensuring that they do not get up after the first knockdown. For more details, see the author's comments.
