    Default SNES games in BAD shape

    Quick question for you guys:

    A friend of mine recently acquired about 10 SNES games from somewhere. Problem is, the contacts are fairly corroded (it's like they were left outside for the past 8 years). Is it possible to remove corrosion from contacts, or are we SOL here? We discussed possibilities for cleaning them, but since you guys would know, would any attempt to do so be a waste of time or what?

    Since nobody is helping you out here...

    I'm under the impression that SNES cartridge contacts are gold-plated copper. The gold consists of a pretty thin layer and rubs off in parts after a fair bit of use and exposes the copper. In an environment with a fair bit of moisture and oxygen (both fairly hard to avoid unless you vacuum-seal everything), the copper begins to corrode and become much less conductive. A common result is having dark green crud on your contacts.

    Some good solutions to this problem are in this thread:
    http://www.digitpress.com/forum/viewtopic.php?p=365892
    (which is probably why nobody bothered replying to this thread).

    Restoring a good game, in my opinion, is never a waste of time. If you have any particularly valuable games, you might even be able to solder out the ROM chip from one game and put it into a matching board from another (preferably cheaper) game.

    Ah, didn't realize that thread would help. Thanks.

    None of these games are particularly valuable, we just wantd to see if we could get them working. And frankly, after reading that thread, I don't know if they'd be worth the time to restore. It might be easier just to get replacements.

    Once corrosion on metal tracework sets in it's as good as gone. A last ditch effort can be made in buffing the surface with some sort of abrasive to try and get rid of it all.

    I once picked up an Atari 2600 cart (very cheap in a bundle with others) without really looking at it. Took it home to clean it and found the entire contact edge had 'crystalized' into green puffs. One experimental swipe of a q-tip completely swept away any evidence that a circuit trace was once there.

    I once had a SMB cart like that... Well since it was SMB I tried out a toothpick to scratch all the Pins "usable" - and it ALWAYS works now

    open the cart, grab a piece of sand paper, send the edges, clean off with alcohol and put it back together


    or if you dont have a 3.8mm bit then use a flathead screwdriver with a piece of sandpaper. Sand the contacts and clean with a q-tip wetted in alcohol
