I have a lcd tv and shaders on snes, megadrive etc and work fine. but the scanlines in MAME4ALL and pifba look very bad. this is my configuration.
hdmi_group=1
hdmi_mode=1
overscan_scale=1
pifba
[Graphics]
DisplaySmoothStretch=0
# Display Effect: 0 none, 1 scanlines
DisplayEffect=1
DisplayBorder=0
mame4all
display_smooth_stretch=no
display_border=0
# display effect postprocessing: 0 none, 1 scanlines
display_effect=1
any solution, please?
