I’m eager to try this out, but you might also want to check out Steermouse[1], which is a utility it took me years longer to discover than it should have. I’m not sure how it stacks up to this open source project, but it’s definitely been worth the license cost to me over the years.

There are 3rd party apps like Steer Mouse that let you re-assign buttons/shortcuts on a Mac, but I haven’t used them in a long while, so can’t really speak to compatibility. Source: 12 months ago

Will I use steermouse to configure the mouse. But didn’t put any specific configuration for arc. Source: about 1 year ago

Use SteerMouse instead, same developer. Indispensable, if only for the snap-to-default button feature. Source: about 1 year ago

Also, whatever you decide on, I recommend skipping manufacturer software and using SteerMouse instead to adjust sensitivity, acceleration and button mappings. Source: about 1 year ago

However you could get around this by installing something like Controller Companion to navigate around the LaunchBox UI then set it to disable when an app is in full screen. Because your in game controls are handled by whatever emulator you have set up to play the game you selected. Source: about 1 year ago

I thought I needed this and just discovered Controller Companion as a better solution since it enables scrolling with the analog sticks http://controllercompanion.com/. Source: about 1 year ago

Trackball like others have suggested is definitely one of the better options. Alternatively you can use a game controller like a Xbox controller with a bit of software called Controller Companion which works really well. http://controllercompanion.com/. Source: over 1 year ago

I really like the scrolling mechanics that Controller Companion provides (larger deflection=faster scroll). Source: over 1 year ago

Oh, and for remapping, you could leave it on gamepad mode and use something like controller companion: http://controllercompanion.com/. Source: about 2 years ago
