See scaler entry below

[render]
# frameskip -- How many frames dosbox skips before drawing one.
# aspect -- Do aspect correction, if your output method doesn't support scaling this can slow things down!.
# scaler -- Scaler used to enlarge/enhance low resolution modes.
#           Supported are none,normal2x,normal3x,advmame2x,advmame3x,advinterp2x,advinterp3x,tv2x,tv3x,rgb2x,rgb3x,scan2x,scan3x.

frameskip=0
aspect=true
scaler=normal3x
