Yeah, it's basically just a joystick to keyboard converter. Pretty simple, but also pretty useful.
[quote="ranix"]can joystick port 2 be a mouse? maybe what you really need is to make a driver that will intercept one of the axes of the 2nd mouse port and treat that as a scroll wheel[quote="ranix"]
Unlike the Amiga, you can't normally use a mouse in the joystick port. However, you could probably write some software to make that possible - it might mean uploading custom keyboard firmware. MWheel is an already existing driver which converts joystick events into scroll wheel events. It directly scrolls GEM windows, and when there's no window present it will map to up/down cursor key events.
MWheel seems to support several pieces of hardware. There's the "Jerry" hardware which allows connection of a PS/2 scroll wheel mouse to both mouse and joystick ports.
