Cheat Mode - Magical Chase GB: Minarai Mahoutsukai Kenja no Tani e (J) (GBC)

There is another push-button cheat for the following game, but I've had no luck figuring it out. If anyone else would be kind enough to decipher it, that would be cool.

At the title screen press Up, Down, Up, Down, B, B, B, B, Left, Right, Left, Right, A. Then on the next screen a new 4th level select option will appear at the bottom.

New Option:


Stage Select:


That cheat uses 13 buttons, and I believe the new cheat is 17 buttons.

New option has a + beside the words:
