It would have to be 2x as wide as well as 2x as tall (pixelwise). To double the size of the pixel, its 4x (twice wide, twice high…cant double only 1 dimension). Also probably uses sprites, which would have to be redesigned, because they dont always scale nicely.
I wanted to do this with one of my megacommands cause my crappy eyesight.
