ROM/RAM Offsets, Text Tables for NES games

I figured this would be the place to put this, although nobody goes here.

I have recently been messing around with NES games using a Hex editor, but I can't seem to find many places where I could find ROM/RAM offsets or text tables for some games, so if anybody out there somehow happens to know any sites, go ahead and point them out to me (I am hoping to see helpful tips such as "Google it" here soon).

I'll probably post some of my own findings if something interesting pops up.
