I've had 4x atari 2600s, 8x genesis 1, 12x genesis 2, 1x nomad, 1x 32x, 5x NES, 6x SNES, 4x SMS, 5x game gear, 1x lynx, 1x game boy, 1x gba, 1x VB
That's 50 catridge based systems I've had in possession at some point or another. Every single one of them has the same issue. Cartidge-based games simply won't play unless they're cleaned regularly.
Either I'm doing something horribly wrong, or it seems that this is the norm. And if someone actually has a cartridge-based system that doesn't need regular cleaning, it's a miracle.
This includes systems and games I've purchased brand new in the box. Brand new, never used, and they still won't work until cleaned. I remember one time I opened a brand new sealed NES game, and the contacts were covered in oxidation already. I swabbed it with eliminator and the pad turned dark black on the first clean of an unused game.
I thought the oxidation layer built as you were playing it. The electrical contact would attract charged air particles and oxidize the contacts and collect dust. So any time you play a game, you'll probably have to clean it the next time.
Wouldn't sanding/filing increase the chance it would start rusting? And just increase the surface area to oxidize?
I live in Minnesota, I don't think it's that humid up here on a daily basis.
I've wondered about this for my whole gaming life. If someone has a magical answer to why I can never play games without cleaning them, I'd love to know.
