I'm honestly not sure if this is the place to post this; the Genesis naturally has a dedicated area but not the Master System.
So I picked up a used Master System recently. It was pretty dusty but powers on and that's fine. I just finally got some games and noticed that up and the up diagonals do not respond on the left port, and none of the directions at all seem to respond on the right side. Using any number of controllers does not seem to do anything. So, I was wanting to pop this thing open eventually to install an FM card, but ... I admit, I know very little about the system. Is there something I can do to possibly remedy this problem? Where should I begin looking? Is this repairable?
A couple of other questions:
I see the system had a paddle for games like Woody Pop. Does a standard DB9 paddle work in its place, or is the Sega one proprietary?
One of the controller pins seems bent on the system. Any decent way to possibly bend this back?
Thanks in advance for any help you can offer.
