Ebay Trackball speed adjustment

[jaharr01]

Does anybody know how you can adjust one of these in windows 7:

I need to increase the trackballs speed. It moves way too slow to play any trackball games effectively. I figured there is probably a registry hack for it out there somewhere.

You would adjust it in MAME, not windows.

Oh heck I didn't think about that slippy blade, that will definitely help. I wish there was a way to adjust it for pc games and etc. I wonder if I get a ps2 to usb adapter then windows would recognize it and I could adjust it?

Does it not even show up in the control panel?
If it does, then:

Start>Devices and Printers>right click on the mouse
select mouse settings
click the pointer options tab
adjust the pointer speed

This will only affect MAME if multimouse is not enabled in mame.ini
If multimouse is enabled, MAME will get raw input data from the individual mice before windows does anything with it.
If multimouse is not enabled, MAME gets the input from the "system mouse" downstream after these settings have been applied. (but there is only one system mouse, so you can't have multiple mice....at least not in windows 7 or older)

Since we are on this topic... I have a regular mouse and a trackball hooked up to the arcade. Sometimes I need the extra usb port on the computer so I unplug the mouse, which screws up the trackball by changing it's number around. Is there a way to set mame to just use input from all mice?

see above.

TL;DNR - multimouse=0 in mame.ini

I went to devices and printer, not there. BTW it's a ps2 mouse. multi mouse must be enabled because I can use both mice on the desktop at the same time. I wonder if the PS2 is set wrong in the bios. I could probably get a ps2 to usb adapter, then it would show up.

multi mouse must be enabled because I can use both mice on the desktop at the same time.

That is always the case.  Has nothing to do with enabling multi-mouse in MAME.
If multimouse is enabled in MAME, you'll see a number after the mouse where the axis is mapped in MAME.

Well, I wonder why it doesn't show up in devices?

^This -- in windows all mice (trackballs, etc.) will act as a single system mouse (so they all work but moving any one moves the cursor etc.) - Multi mouse setting in MAME allows MAME to intercept and interprete the multiple mouse devices as seperate devices, rather than seeing them as the same. So you want to change the system mouse setting in windows as described -- Here is a screenshot (sometimes easier to see rather than read !) of where to find the setting in window 7 (it is similar in Vista/XP IIRC)

It doesn't show up as a separate device because windows sees all mice as the same device.

Thanks that worked finally

AHA. I tried mashing the button inside mameUI and it had no effect but changing it in the text file did. I haven't checked the guns, will this interfere with aimtraks?

If they're showing up as mice, they'll only be able to control one pointer.
Both guns will control the same crosshair.
