I used the debug feature of the UltraStick plugin. Like you said, when the plugin sees "trackball" from GameEx, it sends the mouse map to the u360. According to Ultimarcs website, "Input Mode: In this mode, you can connect 8 buttons to this connector, using the optional wiring harness. Each button appears as a gamepad button on the PC. Each button is independently de-bounced using a state-method for maximum roll-over response. The 24Mhz CPU and high-speed USB 2.0 interface on the Ultra-Stik 360 ensures top performance. Generally you would connect the play buttons, plus start, for each respective player, to each UltraStik 360. If you are using the special Mouse Pointer Map, buttons 1 to 3 become mouse buttons (Left, Middle, Right)." It also seems to disable/not use the other buttons. Is this correct? I have my P1 coin and P1 start mapped as inputs 7 and 8 to the u360. With the mouse map, I cant use or remap the buttons 4-8 as they are disabled. Centipede, Millipede, Blades of Steel, etc work fine because they are actually getting the joy8way map according to the debug mode. I can use my buttons fine. Can I turn off the default mouse map being sent for a trackball game?
