Heres the uploaders notes:
This is the complete WCS loader program and driver set. The last one we made before ThrustMaster was sold to a French company.
I was formerly the Direct Order/Customer Service Manager for ThrustMaster, Hillsboro, Oregon, USA.
Remember to restart in DOS MODE when installing under OSR 2 or Win 98. Will NOT function under NT.
If Privateer 2 is a proper windows program (not a dos program that runs under windows)
then any modern joystick will work I would get a Hotas
