Moto GP2:How do you unlock Legend?

[Matt Freegard]

It says beat the championship on the champion difficult which I have done but Legend mode is still locked.

How exactly do you unlock it?I didn't get a point on Donigton,does that make a difference?

If anyone has unlocked Legend difficulty,please let me know how you did it!

"Shameful bumping"

Seriously,this problem is doing my head in!I want my custom rider to be the best he can be but I can't get all the points cause I can't unlock Legend mode so if anybody owns the game and has unlocked lengend mode hurry up and tell me how you did it!

Please?

Complete all the challenges and the last one will be called legendary mode.

Also does anybody have any cheats for that game. I wanan unlock the practice level, all riders, effect, bring ding ding. Well everything. That game is too damn hard for me. HELP
