This time a game with no improvement. Mike Tyson's Punch-Out!!

MMC2 (the memory controller chip used by this game) is compatible with the overclock, and this video shows it. I state this for it's reliability on latching "FD" and "FE" on the bus (sneaky method used to bankswitch gfx), which still works, even though there is a potential for de-syncing...also why the cut scene is shown (idk if the latches are used there though)
