My nephew wanted the game, so I got it for him. He's a little young for it really, but He loves playing. I tried the code to "unlock all" but can't seem to make it work. Anyone know what I'm doing wrong? Here's what I found...

MX Superfly - Full Unlock
Enter the following into the main menu: X, Y, then
L + X, then R + Y. All tracks, riders, bikes,
and minigames will be unlocked

I've tried it over and over, and it just won't work. If anyone could help I'd really be grateful.

Thanks, and Merry Christmas!!

Are you sure you've been following all the directions? Then maybe it's just a fake code. There are many fake cheats that are made up and this might be one of them.

Here are some cheats that might be real. I still can't be certain about the validity of any cheats because I don't have this game.
