Is it the USB version Sidewinder stick, you have?
As for still using gameport controllers with a game port to USB adapter... I am still using my 22 year old CH products (non pro version) gameport rudder pedals with a 4 selectable options gameport to USB adapter in Windows 7 ult. and in Windows 8.1 Pro, both in AH2 and in the AH beta, with no problems....
I was able to rig my old CH Fighter stick and pro throttle that was game port hook-up via using my old Thrustmaster Gaming pci slot dual gameport connection with speed adjustment dial for a short time back in the early months of Windows 7....
It was a task to get it to work and even harder to help talk others through the process of getting it to work over the phone.... I finally gave up and used the last two gameport ch hotas systems for spare parts... I gave 2 or 3 of those setups away during the end days of winxp switch to Windows 7 (had others donate/give their gameport setups to me to donate to the community)
That was a while ago....
I would like to get some of those ? VKB rudder pedals like GMan is using, since they work like my old ch pedals...no push/pull... they are more precise movements using your ankles, more
Than your legs...
Sorry about that, I got on a rambling rant there
