Make OS 8 and OS 9 support mice with scroll wheels and secondary buttons (right click). Also adds support for joysticks.
If you use modern mice (which are designed for screens with a greater resolutions than those in the OS 8-9 days), you might find that the pointer moves too fast, even when set to the slowest speed. USB Overdive can also fix this, because it adds more custom speeds!
May not work correctly with emulators.

Emulating this? It could probably run under: QEMU
