you do tricks on a gamecube controller using the dpad. up does a backflip, down a frontflip, left spins left and right spins right.
to do a wheelie with a bike you have to press the up dpad so i'd advise making that one the priority. for POW blocks any dpad input works.
i am curious however how this game plays on keyboard though, haven't tried that yet.
"Keep on gaming, but never become arrogant!"
Nah, I meant is it possible to play with keyboard, without an actual controller, though I've already found that yes, it is.
Now a new question:
How do I do tricks out of jumps?
Cuz I haven't played Mario Kart Wii in a long while and don't remember how it's done.
