Been trying to help someone else figure this out and I actually hadn't setup 132 yet, so I threw it together quickly and can not get the Megatouch or Touchmaster games to recognize the touchscreen.
Versions 128, 130, no problem.
I noticed the "Toggle Crosshair" option in the User Interface was no longer available in 132. And that is the only difference I have come up with as of yet.....may not have a darn thing to do with it, but there is usually a crosshair visible for me during those games. It'll pop up briefly and then disappear now. And even while it's there I can tell that the touchscreen isn't recognized.
Can anyone clue me in on what else I may be missing?
Do the update .diff patches have a fix/change for this? (which I don't know how to install yet anyways)
Forgive me for sounded ignorant.....but I am.

(I don't keep up with MAME stuff well)
