-Separate each possible boards (wheel, joystick, skipad, billboard). -Defined a Driveboard type in Games.xml for each games. -Due to the refactoring, Driveboard Savestates have changed (a common base data + a specific board data are saved). -Backwards compatibility with previous save states is maintained. -Driveboard rom section is no longer required anymore. This disables Driveboard emulation in case the rom is not found. -Added Billboard emulation (vf3, vs2, fvipers2, von2). 7 segments and lamps Outputs are redirected to Supermodel outputs. -Changes project to C++ 17 standard.
