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...
