I like how the stretching is correct and everything. I don't understand why nearly every emulator has to default to this stupid fake "select some random columns" stretching that not only looks awful but doesn't even remotely resemble anything in reality.
But yes I think something based on KnT (Kamigami no Triforce, Kaze no Takt... wow, that's terrible) would be better, not because of the FC's limitations (we can ignore some of those), but because it "fits" better? I dunno.
