I sold my NES a long time ago with all of the games, but later regretted it. This is my NES I got from a yard sale then modded for stereo (http://www.chrismcovell.com/nesstereo.html).
Since value of NES games went back up (they were down while virtual console was releasing many NES games), I can’t afford to get all the games I had before, even online or at flea markets.
