you guys are doing good work with this, but i have to ask...are your settings for EVERYONE?
I notice you are using component cables. what mode are you running the emulators in?
I personally run in either 480p or 720p, no higher, on a Mitsubishi MegaView Pro 37 inch presentation monitor. The monitor is CRT, and native 4:3, but it is a MONITOR, not a tv, so certain things such as overscan do not actually apply to me.
I run 480p and 720p using component cables out from my v4, 128mb xbox to an X2VGA2 box, and then from there to the monitor via BNC connections.
the monitor has some capacitors going out on it, and it's native position is slightly left of center, but on a system with UnleashX on it with no screen positioning done, the screen has 0 overscan.
just curious....personally, i don't need all the old school look, but i do want correct proportions as much as possible, relative to resolution, and i want the best possible look i can get (less jaggies the better) without loss of clarity.
thanx for your hard work
