Small keyboard delay / Mame.87 Help :-(

[Darth Nuno]

Hi there,

I'm using now a new configuration on my Gauntlet Legends mamecab.

To display the picture on the WellsGardner 7501 mid resolution, I'm using the fabulous Universal Video Converter from happs.

In order to have PERFECT/SMOOTH horizontal & vertical scrolling I set the option 'synch to monitor refresh'
My monitor display parameter is set to 60Hz, like my UVC.
The animation is fabulous, perfect but I note one problem... The input control seems to be a little delayed :-(
OK excuse me for my bad english... Let's give an exemple :
When I'm playing Galaga88, I press the fire button on my ps2 keyboard ( not using ipac or other encoder yet ), the ship seems to fire with a slight delay, maybe 0.2 or 0.3 seconds after the key pressed ...
If I remove the option 'synch to monitor refresh', everything goes ok, but I got some display problem while fast & smooth scrolling...

Any idea about the problem ?

Many thanks...
