   1 //JOYC.C for D1_3Dfx and D1OpenGL
   2 //D1_3Dfx is a Win32 executable using Glide and DirectX 3
   3 //D1OpenGL is a Win32 executable using OpenGL and DirectX 3
   4 //This joystick code should run on DirectInput 2 and higher
   5 //We are not using DirectX 5 for now, since we want to stay compatible to the HH-loved Windows NT :).
   6 //So ForceFeedback is not supported
   7
   8 //Notes:
   9 // 1) Windows DirectX supports up to 7 axes, D1/DOS only 4, so we needed to increase the number to 7 at several points
  10 //    Also JOY_ALL_AXIS must be (1+2+4+8+16+32+64) in JOY.H file
  11 // 2) Windows DirectX supports up to 32 buttons. So far we however only support 4. Adding support for more should be however easily possible.
  12 // 3) _enable and _disable are not needed
  13 // 4) joy_bogus_reading is not needed, so all calls are just removed
  14 // 5) The joystick query goes over the DirectInputs function
  15 //    MMRESULT joyGetPosEx(UINT uJoyID, LPJOYINFOEX pji);
  16 //    All functions reading over BIOS, including the ASM code are removed
