Am I correct about the following :

DOSBox's Thrustmaster emulation supports three axes, four buttons and a hat. I understand that the hat functionality takes up an axis and uses fixed resistance values. So the three remaining axes can support horizontal and vertical movement and a throttle. Thrustmaster's product range for the gameport included the Flight Control System (joystick), Weapons Control System (throttle) and Rudder Control System (pedals).

DOSBox does not support RCS (which would overlap with the hat and/or third axis) or the Thrustmaster digital programming mode (which would allow the rudder, extra buttons on the throttles or more advanced joysticks to work)
