I appreciate the response, but its not working. I feel like i'm going to pull my hair out. I feel like i've done everything that i've found online, including editing the config file to enable mouse, multimouse, etc.
While trying to edit the inputs in Mame via BB, it doesn't even recognize the trackball when trying to set the X and Y, even though it already says "mouse X" and "mouse Y".
The fact that the trackball isn't even being recognized within Mame feels like a hint, but I've manually enabled trackball as mouse countless times.
Could an issue be that I'm not playing in as an admin user in windows?
