They do not send a proper analog signal, I guess, otherwise they would just call them "analog". Do they have a few fixed levels? How does the Windows Game Controllers applet (joy.cpl) see them?
They are analog. When used on linux, their values change from -32768 to 32767 depending on how much you press them. Same for the X and Y axis of the analog joystick. On windows they work the same.
So I assume the issue in this thread is not converting digital to analog, but merely converting USB to Gameport?
More like converting a digital USB gamepad into analog gameport gamepad.

And in that case, you basically have two options:
- Add hardware, i.e. use an active USB-to-Gameport adapter
- Remove hardware, i.e. disconnect everything USB-related and connect a Gameport cable directly to the potentiometers and switches
Option 1 would be preferred, since destroying this gamepad just to use it with DOS would be pointless IMO. There's also option 3: create software to do the conversion inside the PC itself, however that does not seem to be easy to do.
