I’d like this to be a thread about ways to keep your consoles and games clean and running, how to solve issues that might crop up, and just general knowledge on how things work. There’s a lot of junk advice out there about how to do certain things which would surely do more harm than good to your retro collections, such as cleaning the cartridge slot with sandpaper. I’ve often thought about creating a topic on this, as Retro is one of the more sensible gaming communities and, of course, has a lot of members with retro SEGA hardware which requires upkeep to ensure they continue running 20+ years later. I guess I’ll start as I’ve got a few questions about the (copper?) cartridge and game contact pins. I keep my collection in good condition and clean the game contacts maybe a couple times a year with earbuds and pure isopropanol. I recently started regularly cleaning the cartridge slot pins of my Mega Drive I to see if that made a difference to the amount I’d have to clean the games. I’m finding a lot of black residue on both which I presume is oxide from the contacts, but even after multiple cleans a few weeks apart there’s a lot coming off. I recently bought a few brand new cartridges (EverDrive, Aladdin’s rerelease, Mega Turrican DX) and after a few uses I found the residue on those too. So I guess my question is; is this frequency normal, and is there anything I can or should be doing to minimise it?
