1, 2, and 3 each have progressively more descreening, which makes them each a little softer, but it depends on if you just want a nice smoothing of the print screen but it's still visible (like #1), or have it almost completely removed like #3...

Maybe worth to show the examples in png to compare the pictures "as is" without jpg artifacts? And is it possible to use the pngs as backgrounds in MAME? It's a bit weird to see the huge lossless laserdisc dumps (where each frame is, in fact, a lossless-compressed picture) and these single-screen artworks in jpg
