i edited dosbox.conf a couple times and i cant get it work like in windows xp, i have windows 7.

fullscreen=true
fulldouble=false
fullresolution=0x0
windowresolution=0x0
output=opengl

machine=svga_s3
captures=capture
memsize=16

frameskip=0
aspect=false
scaler=none

I am always have black areas at left and at right side, surface, openglng, ddraw, overlay can't fix it, and overlay doesnot smooth graphic like opengl, in windows xp it does. also openglhq even not work.

Resolution 1366x768
I want 320x200 game to be stretched to entire 1366x768 resolution using opengl without these left/right huge black borders.
