Hi I decided to get out my old super nes to start playing again the console is working fine and 2 of my games but all my other games are not working all of them I get nothing not even sound and 1 of them I get the Nintendo sign at beginning and sound but no picture, please someone tell me I can fix this as desperately want to play the old classics, I have cleaned all the game chips still nothing thanks to anyone who can answer as I’m baffled as everything else works
I found this video on how to clean cartridge correctly. It might be usefull : https://youtu.be/Ar15T-Wl2EM You can try with IPA, an eraser or by scratching the dirt from the contact.
