You'll need a turbo pad and a whole lot of patience. As soon as you get in the first level go to a place where an infinite supply of ants charge you. Turn the turbo on so it keeps hitting the ants with the sword. Now just change the channel and watch TV, If you can't watch tv without turning off the Sega, just unplug the hookup to the tv in the back of the Sega. After a few hours you will have the highest level possible in the game ithout even beating the first stage.
