I Have a CGA 25" monitor, Arcade Vga 3000, mame 0.144
And I have used M.A.M.E. Resolution Tool to create the ini files.
For the most games the res is perfect for some close and others like, frogger they seem totally off.
I used the M.A.M.E. Resolution instructions to weed out some unusable resolutions for my standard arcade monitor.
How do I know my V-size setting is correct .. for example on games like final fight there's a little black border on top and bottom but for mortal kombat games it's perfect.
So do I find one game then set V-size and change res for other games? whats the best way?
