ps/2 trackball fire button
mclaught:
I have the imperial ps/2 trackball hooked up, only using one button (green wire from the trackball) and that acts as my left click button for windows. I also want to rig that same button up to SW1 of my IPAC. However, when I tried this, neither the trackball nor the keyboard controls would work. I ran a wire from that NC tab to SW1 and kept the green wire on. I tried a couple different ways to ground it, nothing seemed to work.
Is it possible to have one button work like this? Any advice is appreciated, as always.

When I configure a game with -mouse, it assumes that the left click button is the fire button. No need to wire to S1
mclaught:
nope, the mouse button works correctly in windows but it won't fire in mame. oh well, thanks for the reply anyway.
mccall:
Shouldn't you be using NO (normally open) not NC (normally closed) on your switches?

This is answered in the mame faq; read the faq
Just for you, special instructions:
Press TAB, go into "Input (general)", and set "player 1 button 1" to "L ctrl OR mouse button 0": go to player1 button 1 in the menu, press [enter] key, press the player 1 "fire" button on your CP, wait until "Lctrl" shows, press enter again, press the trackball "fire" button.
You can also do this with ctrlr ini files, instead, but that will take a little more understanding. To learn more on this read docs/ctrlr.txt and easyemu
