Having only recently joined the world of HDTVs I've become acutely sensitive to screen stretching. Before that I played all of my older games on a pretty good SDTV. I've been searching for emulators that scale by integers not by stretching. Most people refer to the 4:3 to 16:9 stretching when they talk about it, but I mean stretching of the individual pixels at all (save for some 4:3 correction when applicable). I've been searching for emulators that allow direct scaling (e.g. 2x, 3x, etc.) in full screen mode because I'd really like to play my old backups on the new TV via HDMI. It seems that most emulators, when switched into full screen, at best, will only maintain aspect ratio, but stretch vertically. Granted, I'm only actively searching for these when I have a particular game I want to play since all of my emulators are drastically outdated (ca. 2006). I have found a few that will scale pixel-accurate and I wonder if anyone else has the same issue I do and have found some on their own. VBA-M allows a 6x scale in full screen which leaves the games looking large and lovely on my 42" plasma. The Metroids in particular. FCEUX worked well, but only in windowed mode (iirc). Megaman looked better than ever. Snes9X wouldn't work properly with a combination of 4:3 correction and direct scale. One option would always take over the other. I've been trying to find a PSX emulator that can do this, but since the resolution in any given game itself changes, I don't think it'd be able to do a direct scale anyway. The best I could hope for would be a smart scaling (for instance 320x240 goes 4x and if the next screen is 640x480 it goes 2x). Has anyone else found any emulators that can output a perfect pixel fidelity to a 1080 screen? I haven't had a try with any Genesis emus yet.
