I recently picked up a Sears Video Arcade II system in a lot and I am having some control issues with it. The games boot up fine, and the controllers are recognized, but for some reason I can not move right at all. All the other directions and buttons work, but I just can't move right. I have tried both Sears controllers that came with it, along with a known working Atari joystick and none of them will move right. It happened on 3 different games I tried.
All the pins in the port appear to be there and undamaged. I cleaned the pins with a toothbrush and alcohol, as well as reflowed the solder to the pins on the board, and cleaned the cartridge slot really well. All of this had no affect.
I'm at a loss as to what it could be. The only other notable thing is that it didn't come with an original power supply, but had a Genesis model 1 power supply. I heard that these were OK to use on the system. If it's the power supply that is the issue, I have no problem replacing it. I just don't want to sink the money into an official power supply and find out that it wasn't the issue.
