Setup Gravis Eliminator PRo (USB) with VBA

[skyyman]

I just bought a new Gravis Eliminator PRo (USB) for Visualboy Advance and I can program all the buttons, but I want to assign the 'Z' keyboard button to the '2' key on the Gravis and the 'X' key to the '3' key on the Gravis.

It seems that it will only assign the 'X' key to both the '2' and the '3' buttons on the Gravis only and so I have to assign the 'Z' key to the '4' key on the Gravis.

Any help greatly appreciated or if anyone has some presets that I can import then that will be even better.
