Pin corrosion and broken board traces
So I picked up a copy of Contra III at a thrift store today and was super excited because I've been looking for a cheap copy in the wild for a looooooong time. Anyhoo, I get it home, do my usual cleaning routine and it doesn't start up. I tried alcohol, the 1-Up cards, brasso, etc., basically everything I found on NA about cleaning a stubborn board. Aside from transplanting the chips, resoldering the pins, or just buying a new copy am I missing something?
Otherwise, I will probably just sell it at a hefty discount since I can't get it to work...

ill buy it for sure. pm me if you cant get it working cause im intrested but! before selling it. try some 0000 super fine steelwool. that will get it working as long as its not another issue.
I'm guessing that is finer than the SOS scrubbers? Do you think those would be bad to use?

sos pad are thicker but it should be ok. go on and try that.

Should I try to rinse out the blue chemical first or just go for it?

There's a good chance the there is a broken trace looking at those pictures. If you have a multimeter, you can check the continuity from the pins to wherever they lead, it's really easy.
I no haz multimeter...unfortunately

Since I've never tried the steel wool approach, is there a certain point that I need to be rubbing the pins to or warning sign that I've scrubbed too much?

well its already in bad shape so just rub it till the rust spots turn to a copper color but only the spots not the pin its self. generally it takes alot of rubbing to damage the pins. just do like 10 scrubs on each side or so. once your done take a paper towel with windex and clean the pins of the steel whool debris

Looks like a broken trace to me as well. You'll need to reconnect the trace with a mod wire. On the 10th pin from the left in the 2nd pic, look at the green trace coming off the pin. Looks severed. And possibly the 13th pin trace as well though it could just be corrosion. Do you know how to solder? I'd try reconnecting the broken trace on pin 10 by scraping a little of the masking off on each side of the break and connecting a little wire.

Quite a few suspect ones in pictures.

Welp, I tried scrubbing it with steel wool and no luck. I would scrub a handful of times, clean it, and test it like you said with no luck each time until I felt like I was about to do even more harm...

It does look like you might have some broken traces. In that case you could try to repair them but its a little more indept than im going to go into. but it my fix it. Definitely check with a multimeter. get the cheapest one you can find if all your useing it for is continuity. It could just be the solder mask.....but it looks iffy to me....

Definitely could be...I have close to zero soldering skills

In theory could you place a teensie weensie bit of solder on top of the rusty area to try to get the current to flow? If not isn't there some kind of pen you can use?

Hahahaha I was more directing it at the experts dude.....would just hate for you to have to ditch a Contra III...
Cart has been sold and is going to a better home that will heal it...lol
I also changed the title of the post so that it might be easier to find in the future if someone searches the same issue.

Yeah, you could definitely do something like that. Would just need to expose the trace a little by scraping the masking off with an xacto knife to have something to solder to. Either way, if you were to just put a little solder blob or a wire, for something that tiny i'd add a drop of Super glue over it after to help keep it in place. I've never used the pens before but it could work I just don't know how long a connection would last with one.
