I really don´t know. You could try it out now and see if it runs now, of course. I hope it was nothing but dust in your case. And maybe the scratch is not an issue at all.
I understand that the thin gold layer on the contacts could potentially wear off but can this happen even after 10000 times in and out, realistically? If so, then I believe everyone who can produce platines could possibly renew the gold layer. Lynxman has hinted at this on one occasion, and he produces Lynx homebrew carts. At any rate, it´s not at all a common issue.
Now that I think of it, there is one homebrew cartridge (Yastuna 1), and my copy I often have to insert firmly more than once otherwise it doesn´t boot off. Cleaning the (brand new) cart has not helped there, only repeated insertion.
It might be my Lynx´ cartridge slot. After all, 20 years are 20 years and second hand is second hand. These problems are rare, maybe once every 20th time I insert a cartridge. The GB Classic has a higher miss rate, so I blame the cartridge slot contacts.
How to correctly clean the cartridge slot, I have no idea. Perhaps with a q-tip or a dry toothbrush? Surely there are some guides out there, preferably for the more notorious contact issue consoles, like NES.
