What, 1280x256 isn't wide enough?
PAL with max overscan is 1448x566 in super-high-res laced, I pulled it down to 1366x566 on a CD32 hooked to a 40" Sony LCD TV using S-video, and it was actually quite good, and amazingly enough, flicker free.
Anyways, 4:3 aspect? Only NTSC has that, PAL is 5:4 (or rather 5:2 for flickerfree non-laced)
