Hi all.
I have a problem of this type;
my cab is configured with a 24khz monitor fixed on which I run almost everything in super resolution @ 2560 X 384 with orizzontal games all is ok and upscaled, but not with vertical games.
Vertical games occupy only a part of the screen probably because groovymame manages to center the 320 vertical lines in the 384 available and then the image is resized smaller.How can I do to ensure that the whole screen is occupied by the image of the game? And groovymame create a modeline with the correct refresh?
Thanks!
