Forcing to desktop 640X480.

[Donizete]

Please, can anyone help me?
Even setting the resolution on Demul's video option to a lower value, when full screen launching it keeps 640x480.
I moved my desktop to 640x220 to do a test and it is even at the working area resolution.
My interest is in Capcom games, so it is insisting on maintaining a lower resolution. No Mame looks so beautiful, but it hurts to see the jagged graphics on the Demul 640x480.
In Readream I also got the same result.

I guess your mean Capcom's 2-D fighting games on the NAOMI hardware, which are natively 480-P-displayed, despite the upscaled sprites. The only one you might have luck with is SFZ3 Upper.
