Play The Japanese Version
To play as the easier Japanese version, sequentially and repeatedly press B, A, X, Y at the white screen with the Jaleco logo until it disappears. If done right, you'll arrive at a glitched screen. Now, press Start, then Down three times and Start again. You'll be at the options screen and when you exit, you'll see the Japanese title screen. Now start your game and enjoy the original version of the game.
