Hey there.. just bought a turbotwist2, and was all excited about the z-axis... but it doesn't work in mame.. So, with a little investigation, I realize that the spinner work on the z-axis in the rest of my computer, just not mame. Neither does the mouse wheel.
Now, I should mention I am using linux, and have tried xmame.x11, xmame.SDL, and advancemame... all v.106, all won't see the z-axis.
Before I drop money on an optipac, is there something I can do? Is there something I am doing wrong?
