Found a Creative sound card with gameport at a Goodwill for $5.00, so now I have a working gameport again. Unfortunately, Both of my F-16 FLCSs have a twitchy pot. One likes to dive at random while the other jerks to the right. Only happens when centered. They are fairly unusable at this point because of it.
I might swap them around so I have both good pots in the same stick, or maybe I should look into cleaning them.
