Yu Yu Hakusho: Dark Tournament Cheats

When playing as Mankintaro after you have taken damage, back up and execute his regeneration move. Pause game play while still holding the buttons needed for using regeneration. As soon as the game is paused, you do not have to hold the buttons to continue regeneration anymore. While the game play is paused your character will still continue to heal, you can do this as long as you want up to full health.
