Gamepad Axis Mapping

I am using a Logitech Dual Action gamepad, and whilst the analogue steering was easy enough to get working on a joystick, the accelerator/brake is proving more difficult.

The game seems unable to map two actions to the same axis, which means I can use the y-axis (upper) for the accelerator, great, but if I try to use y-axis (lower) for the brake, this over-rides any previous mapping, and the accelerator no longer works.

moveMap.bind(%device, rzaxis, "I", accelerate);
moveMap.bind(%device, rzaxis, brake);

Does anyone know of a combined action (like joy_steer which combines left & right in one action) but for accelerator/brake?

The action 'joy_accelerate' is used in the mapping for the Hitec Aurora 9 R/C (RC-Joystick) but is unrecognised when I try it for my gamepad.

Any ideas would be welcome

 

This solution should work, I know, I've done it gas-and-brake-same-axis
