Linux on the Nintendo GameCube and Wii

Did you all just get this email? I wrote it 48 hours ago. Very old. 
Just don't read it, everything is fixed. Read the news on the site 
instead! :-)

the YUYV conversion doesn't really need floating point.

you can simply do something like :

y =3D (299 * r + 587 * g + 114 * b) / 1000;
cb =3D ( -16874 * r - 33126 * g + 50000 * b + 12800000) / 100000;
cr =3D (50000 * r - 41869 * g - 8131 * b + 12800000) / 100000;
