Vertical Twist / Serial Port Joystick interface

Postby sirbod » Sat Apr 07, 2018 7:09 am

Does anyone have the games developer SWI documentation for this Joystick interface, in particular what the table passed to VTJoystick_Define specifies.

The driver disc doesn't go into detail on the SWI's, but several games use Define so there must be detailed documentation on it somewhere.

Is this document any help?

Appendix C looks as though it might be relevant :?:

Unfortunately not, the documentation that came with the interface doesn't cover VTJoystick_Define and only briefly mentions some of the other SWI's.

Thanks for the link though, I believe that's possibly one of the last revisions of the manual.
