A good Nes Site?
 

Anybody know of a good nes site. I just recently picked up 2 of the old systems, and looking to figure out what all accesseries came, what if any modifications I can do etc.

Like I could really use some cord extensions, but can't seem to find them except on ebay for like $15+ for 1!?! I don't even remember if they really existed or not.

Game sites are welcome too. Thanks.
