Je me réponds tout seul mais ça pourrait vous intéresser. Voila ce que j'ai trouvé sur un forum.
Hey all, I've got one balance board working with family ski. The trick is on the menu screen (where it lets you press a + b) click on the balance board icon, make sure the board is switched on and that you're NOT standing on it. Press a through the various messages and it should calibrate it.
Then select freestyle or whatever you want to do, select your character and daytime type, then when another 'no error' box pops up step on the board and press a, it'll then calibrate it to your weight.
When the game starts you should find the balance board is your left/right and your wii/nunchuck control speed.
Now... where I'm stuck is trying to get a second balance board to register for multiplayer. I saw a clip of USA today or something where they had four people skiing together on balance boards, I assumed the game was Family Ski and bought two boards accordingly, but I can't get even get two boards connected to the wii at the moment. Anyone had more luck than me?
Testerai ça ce soir en espérant que ça marche.....apparement, c'est injouable avec la balance...on verra bien!
