Sorry for the delay but I decided to change the implementation, so I don't need to change every game driver.. =)
There is now two new options for mame and a new line will be added in the MAME.cfg under [Config] section
This is trackball_XY
if trackball_XY = yes then Mame will use dial/paddle/trackball_X (on a secondary player) to the Y-Axis of a Mouse input.. basically X-Axis is rotate/steer left/right on player 1, and Y-Axis is rotate/steer left/right on player 2.
To use Mame defaults delete Games tested and worked.. All SNK rotary games, all DataEast rotary games, Sprint, Sprint 2, Super Sprint, Championship Sprint, Badlands, some games might be a bit weird with trackball_XY, but its primary idea is for people that have 2x Happs optical joystick and/or 2x360 optical wheels.. (lucky berthas!! ;) Let me know what you think..
