    256×240 optimised can only be integer scaled, therefor AR can never be correct in this mode. You can see the multiplication factors here (bottom of page): http://junkerhq.net/xrgb/index.php?title=Optimal_timings

    For reference, AR of SNES visible area should be 256/224 * 8/7 = 1.306122449

    To reduce jitter in generic mode, try toggling TVP H-PLLx2.
