Multiple Mice with Windows Mame

Note: All tests were run under winMe.

Test runs results:

Physical mice hooked up					Mame Sees
Serial	PS/2	USB 1	USB 2	USB 1 w/ ps/2 adapter	mouse[0]*	mouse[1]	mouse[2]	mouse[3]
X					X
	X				X
		X			X	X
X		X			X	X
X			X		X	X
X	X	X			X	X
X		X	X		X	X	X
	X	X	X		X	X	X
		X	X		X	X	X
			X	X	X	X

Notice the last line: it seems the usb mice need be plugged into the usb ports, and not in the ps/2 port with an adapter, to been seen as a separate mouse.

serial mouse: generic
ps/2 mouse: logitech marble+
usb mouse 1: Kensington Expert Pro
usb mouse 2: Logitech First/Pilot Wheel

* The "system mouse"; it reported all movements/clicks from all connected mice, just like in current mame, windows, and almost all applications.

Individual mice inputs:

	"system mouse" mouse[0] *	mouse[1]	mouse[2]	mouse[3]
Serial mouse	X
PS/2 mouse	X
First USB	X	X**
Second USB	X		X

** Sometimes had to unplug and replug to get data out of it, usually after I plugged or unplugged another mouse.

Conclusion:

USB mice, baby!

Windows finally can have multiple mice for mame, but more programming is needed:

cfg input settings: which mouse is assigned to which player (analog joysticks can use the same thing)
special cases:
- if only one usb mouse is connected, mame thinks there are two mice
- if one usb and one serial or ps/2 mouse are connected, mame thinks there are two mice
- saved cfg setting have more/different mice than currently connected
More coming.
