Thanks to scott, I just installed the Wii Internet Channel for free and with the last update (yes, even here in France)!
I planned to install it for so long...but I wasn't able to admit I had to pay for it!
It's a very good news (no just for me) because it means almost any Wii player will now be able to play Flash Lite games, for free.
A better stuff would be to Nintendo to include the browser on the next release of the Wii (with system 4.1+)
Now, the only problem is to find how to attract Wii gamers to our site.
All the Wii only websites I found about games are full of all Flash 6 games....
