One last hangup on my cab...

joecitizen:

Is there any way to disallow trackball input from the opposing player when it's not their turn?  As it stands, both of my trackballs register input now and function well except for this one small detail.

I'm using the newer optipac on a cocktail cabinet with a trackball at either end.  The jumpers are set to "serial" and "player 1", and I'm running a serial to usb conversion cable from the connector marked "serial/usb".  Is that the proper thing to do? I had the jumper on usb and I had no input.

I'm running the latest mame build on windows XP with MaLa as a frontend.

Any advice is greatly appreciated... thanks.

DaveMMR:

Are you Mame settings listing both trackballs?  If so, hit tab and setup the game so that alternating players use the same trackball. 

2P alternating TB games don't have two trackballs, so the game hardware and therefore Mame doesn't know that it should "turn off" one trackball when the other one should be used.

Here's how to fix it...

1) You must use the USB setting to get two independent trackballs with the Opti-PAC.

2) You have to go into the MAME configuration menu and map your trackballs the way you want them to work.  Older versions of MAME were not this way.



joecitizen:

When I switch the jumper from "serial" to "usb", neither trackball affects the cursor in XP, whereas under "serial", they both do.

Is there a step I'm missing?

I understand configuring the controls under mame config, I guess I just need to figure out how to get the trackballs to send a signal under the usb setting.

Under control panel/mouse/hardware...

When the serial jumper is set, I get two listings

1) HID-compliant mouse at loc 0 (my wireless mouse I guess)
2) Standard serial mouse on prolific USB to serial comm port (com3)

When the usb jumper is set, I only get the mouse at loc 0
