They then go on to say that for most applications (to reduce EMI above 1MHz) you should include a ferrite bead followed by a 220pF capacitor to ground on each output. So, "filterless" or not? The latest PicoGAME VGA mini 6 has the SD card supply filter, as do the PicoGAME 1.4 and the PicoGAME  2.0.
