RE: Carnevil monitor issues...

Well, maybe I don't know the answer :)

Like you say, it could just be the monitor, so same symptom, different
cause.

However, the game was twitchy on a 35" with factory settings from the start,
and it showed up a lot more on the corners of the screen. The 'fix' was to
crank the Screen Flash Brightness all the way up. In addition, I seem to
remember the video voltage amplifier dealies (I'm not an EE) being weak on
that game, so we'd usually crank the monitor brightness all the way up to
compensate.

Can't help you with MAME, I'm afraid

Hi Sam,

Yes, we had played with the Screen Flash Brightness - tried multiple
settings both higher and lower - from around 25% up to 90%. Didn't help...

I tried holding the guns up against the screen as well as further away -
no success. The game does recognize the guns over most of the screen at
50% (and other settings) but the corners just seem to be too diffuse to
work, and there is no other way to calibrate the guns!

MAME might work as a substitute (run the 35" off MAME but use the
Ultimarc gun system which does not rely on the tube quality as it senses
the guns position relative to a group of LEDs (very clever that!).

However I haven't yet got a working chd image...
