6 Switcher left player always firing.

Recommended Posts

Well, I spoke too soon. It took me a while to sort out the power supply issues. Put the thing together and ran KABOOM! That worked fine.

 

Turns out the left player fire is always on. Was doing kind of a sanity check with my cart collection. Many of them have not been in a machine for a long time. Discovered that right away.

 

First thought was a stray solder blob. After working on it for a while with a lens, and re-heating the ones there on the DB9 connector, I'm convinced that's NOT it. (I could be wrong on that, but I don't think so) Does it with ANY joystick controller plugged in. Also does it with NO controller plugged in.

 

Probably means static or jus
