Better stay away from USB and connect one of the trackballs to the PS/2 port and the other one to a serial port (or both to a serial port each) and then use AdvanceMAME under pure DOS.

I got some questions to any one running two trackballs and AdvanceMAME. I have a one SUZO trackball connected to an Opti-PAC setup and I initially tried it out with the Cute Mouse driver. It really sucked! The mouse movement was jerky and I was unable to tweak it to feel right. I finally got it right when I switched to a Microsoft mouse driver. I know that the AdvanceMAME and OptiMAME mouse driver is based on the Cute Mouse driver source so my question is if anyone running AdvanceMAME got it working with dual trackballs? And if the mouse movement is smoth? And if so what trackballs and interfaces was used?

: Whoops you're right. For some reason I was thinking the trackballs themselves were sending unique signals but the computer is just polling the port and can't distinguish between them.

: So I guess I should hook up one PS/2 trackball and another Serial one? Will the "normal" DOS Mame under Windows 98 recognize a USB trackball? I have an available Serial Port, USB ports, and PS/2 Port.

: Thanks - Cryo

: : : I'll have two PS/2 trackballs, both connected to a PI Electronics PS/2 port splitter, which then runs to my computer's PS/2 port. From there I plan to use AdvanceMame to seperate and use the two trackball's signals for two-player games (marble madness, etc etc)...

: : That won't work, the trackballs have to be connected to different places, a "splitter" only switches between the two to make the computer think that they're one trackball.

: : : I'm also going to have a Hagstrom K72 encoder. Is there a good reason I should get the K72T and run the trackballs to that before they go to the computer? Is there any difference?

: : If they're arcade trackballs they have to each be connected to an interface. If they're PC trackballs you don't need an interface.
