Quote from: zmaster18 on April 25, 2014, 11:25:45 amI still don't believe it is the RAM adapter, because I never had this problem once when I used this system all these years. The last time I used the system was 2 weeks ago, I don't see how the RAM adapter would suddenly go bad that quick. I still think you need to scrape the surface of the pins in the cartridge connector with a metal file, it works like a charm for me! Although Brasso is great for making the surface of the contacts clean, you may have to get underneath the surface of the pins if the surfaces are a little dull or corroded.
Quote from: P on April 25, 2014, 12:36:06 pmYeah well cleaning the contacts should be the first thing you rule out. Don't use anything but alcohol. 99% Isopropyl alcohol is usually recommended. For polishing the RAM adapter's pins you probably need a fiberglass brush to be able to reach them. That worked for me anyway, and my games doesn't crash anymore even if wiggling the RAM adapter.The thing with the RAM chips is that some probably has a manufacture flaw which makes them degrade over time. This may not be immediately noticeable. I can't help you where to find compatible RAM chips though. However I can say that soldering and desoldering chips is not a good beginners soldering project.Do you have FDS Pro Wrestling available? If so does it have graphical glitches?
Quote from: P on April 27, 2014, 03:19:44 pmThose faulty chips are still a big mystery. I would suggest to ask at a more technical forum about chips. The people at nesdev are often using ram chips and there's lots of technically knowledgable people there.Do you have any way of testing the FDS on another Famicom? Then we could at least rule out your main unit.
