HI RedBaron
Me and my friend both have sidewinder3d pro's and are both using win98 systems. We both couldn't get the sidewinderpro to work in aceshigh. Downloaded the newest sidewinder3d pro driver (swgameen 6.745kb) which said install it, if you have problems then install sw3dpro.vxd (12kb) and it should work. (make backup copy of the file being replaced just encase)
My friend did it, and his works with all button functions.
I still can't get mine to work with all buttons and my game gets a little choppy.
I can still use my sidewinder3d pro minus the 4 bottom buttons if I set it up as
CH FLIGHTSTICKPRO (enable rudders). Computer finds the joystick will no problems.
I have no problems in the game other than the fact that I'm no good haha.
NOTE! I think the site he got the drivers from was
http://www.microsoft.com/sidewinder/ not sure.
Good Luck!
