So, does QEMU support the PC Gameport? How do you get the support working? Oh, bummer… a while back, there were some devs with a work-in-progress branch to add support to QEMU, but it never got through to completion. Here is the trail of their last conversation in the subject.

So, I guess I’ll have to start over implementing it from scratch. It’s not too hard to implement, it’s just getting all the interfaces matched up is tedious.
