Hey guys, I am not sure if you are aware but Stone Age Gamers carry a 72 pin to 60 Pin adapter to play NES cart on Famicom and the connector could potentially be removed to be used on NES related project. I tought some of you might be interested as those adapter are 9.99$ and I know the connector is pretty hard to find. I can't comment yet about the pitch used but I have ordered one to take a better look at them. Some will most likely find that paying 10$ for a connector is alot but at least it could be a potential source that wouldn't involve destroying a game genie or cutting and fiddling with computer edge connector to make them almost the right pitch. And for small personnal project, 10$ would be acceptable for me.
