Does anyone have infos on how many tracks have the PSP version and does they have the same name that the actual versions ? I'm asking that mainly for the level leadeboard.

From what i can find (on a brand new save) there is Safari 1/2/3 Alpine 1/2/3 Tropical 1/2/3 Arctic 1/2/3 Canyon 1/2/3

Lakeside (unlocked after beating masters champ)

I will add the category for the psp then i prefer it has it's own because the gameplay looks quite different it's been ported by Bugbear Entertainment.

Yes PSP version is totally different form the original. It should has his specific page.
