I just got my component cables from nintendo and what a difference it made for Zelda. It totaly gave it a faceleft. The colors are so much brighter and deeper. Anyone with a EDTV/HDTV must be using these to get the most out of your Wii.
On another thread regarding VC games being dark, it seems like the Component cables solves it somewhat. It's still a tad darker but way much better then before.
