I recently purchased a 3DO from a thrift store. The unit has some minor damage. If you're looking at the front side, the top plate on the left side is pulling apart from the bottom part. The unit plays fine. I can boot up games with no problems. The problem I'm having is that the controller I have doesn't seem to be working. I have a Panasonic FZ-1 unit, but the controller is a Goldstar. I don't know if the controllers can be interchanged. If it isn't the controller itself, what other problems could there be and how could I attempt to remedy them? Any advice would be greatly appreciated. Thanks in advance.
