NES frustration

Hmmm, replacing the cartridge connector usually does the trick. I assume you cleaned the contacts on the cart with a 50/50 water alcohol solution as well?

I was using radio shack electrical cleaner in an aresol can. I was just spraying a little bit on a q-tip. Maybe I should not use that...

Not sure, never used that before. I figure if it is getting the gunk off the carts and you are blowing on them and allowing them to dry before you try to use them again that there shouldn't be any damaging effects with what you are using.

Here's the ultimate solution. I NES that was designed correctly in the first place.

Anyhow, it looks like some people on here's advice and knowledge on the subject of cleaning carts far surpasses my general user knowledge.
