Doesn't work with PAL N64s.
After i bought it i discovered that PAL N64s can't output S-video. I think it should be written in the product description.

S-AV/AV
Im using the old tv with composite and s-video input. The S-video makes the graphic much sharper than the normal composite. Really recommend this product if you dont have component/HDMI input on your tv.

i bit better
i have get this cable for my snes and is compitable with all there consoles eccept the nes.
i have test it with the xgabox and supported tv trough scart.
well i must say it,s a bit better than the a/v cable no more noise on screen ennymore, this is a must have cable
