I copied it to the Privateer directory and the game still asked me to calibrate the second joystick (what do you need two joysticks for in Privateer?), but a "copy joya.dat joyb.dat" sorted that out. Now the game works with joystick but it's grossly decalibrated and obviously I can't calibrate it through normal means. In case it makes sense to someone here's the file in a hex editor:
