The reason I asked is because he is the author of MameAnalog+. Might help to get him involved?
I think some people have been after 'updates' as analogmame is currently at mame ver 0.83. Although if there are no games requiring its extra features then it may not be needed.
From what I can see, analogmame works perfectly. It requires HID-mouse devices to be present in the system, and will allow seperate mappable control in mame, which regular mame can not do.
My current issue(s):
Smogs Guncon driver makes the lightguns appears as HID-mice, Acorn's does not.
Acorn's driver calibrates in windows perfectly, allowing precise control of the mouse cursor by either gun.
On my system, Smog's does not calibrate well - the driver seems to flip into a crazy mode 50-75% of the time where you can't control the mouse by anything, and when working, I can not get the cursor to line up well in windows like I can with Acorn's.
jpark, le2 and gollygho do not appear to play well.
jpark appears to have position related acceleration (viewable when using a mouse).
le2 and gollygho appearslinear. They track extremely well, just offset by a huge 7 inches. There does not seem to be a calibration screen for the guns. I would be interested to see how the guns were calibrated on a real system.
