Nintendo Wii : website optimisation

I have an existing video based website that I would like adapting so that it works on the NIntendo Wii web browser. All functionality must be maintained, but the layout and the colours should be optimised for the Wii. The navigation in particular must be updated so that it works well with the Wii controller. Do you have experience in this and can you successfully deliver this? The exitsing website is built using the Cake PHP framework and MySQL database. This must be maintained.
