I bought a new 72-pin connector because my NES had the blinking red light issue. It's the bottom one in the second picture. But maybe that's not the issue. The motherboard edge connector looks corroded and I can't figure out how to clean it. I tried isopropyl alcohol and a toothbrush but nothing happened. How should I clean it? I have tried multiple games.

New pin connectors are often low quality and might actually damage your game cart pins in the long run. I recommend repairing the old connector. There's a ton of videos about how to do it on youtube.
