I’ve got a happ control trackball plugged into the B+ pi via usb and in X, it acts great as a mouse. The left/middle/right buttons all work great and moving the ball moves the mouse as expected. However, in games like centipede that require the trackball, the movement does not register. Am I missing something in the configs to enable mouse support in mame4all? I’m using emulationstation as my front end, and am using the latest retropie SD card image. Any help would be much appreciated. This is driving me a little crazy.
BTW…I’m using the first mame4all command in the emulationstation config file, not the one related to RetroArch although I did try that one on a whim and still don’t have trackball support.
