Generic 4:3 vs Optimized 320×240

[phl0w]

Hi there,

I’m using an OSSC for my 360,PS2, and Sega MD. I’m quite happy with the image quality of all three consoles when set to generic 4:3. However, I read that 320×240 (in the case of 240p signals) should yield the best image quality, albeit at the cost of playing with advanced timings quite a bit. I managed to come up with settings that yield a stable and sharp image for my MD at line5x and 320×240 optim. I am not so lucky with the PS2 though. Whatever I do, the image jitters, or is fuzzy, or missing lines (text being cut off), in short: doesn’t come even close to how it looks when set to generic 4:3. Is there a “best practice” I should go through to come up with a decent image or maybe tried and true settings someone came up with already? I know the OSSC and ps2 are not a particular good match but I only use the OSSC for ps2 games that put out a 240p signal (DDP DOJ, Espgaluda, Gradius V, Ibara), for games with interlaced resolutions I have a GBS-C.

Thanks in advance.

First of all it’s not really accurate to say that the optimal modes yield the “best image quality”. The optimal modes result in an image that’s extremely sharp, rather reminiscent of an early emulator than anything approximating what the image would have looked like on a CRT television of the time. That’s not to say they aren’t useful of course, some people prefer this look, while it is perfect for further scaling or processing or for the direct capture of pixel art via a frame grabbing device or capture card.

For the PS2 games you listed I am certain Gradius 5 is 480i not 240p. Most of the Cave titles on the PS2 also run in 480i though they can be forced to 240p via homebrew software. Check the display on the OSSC it should tell you if it’s receiving interlace or progressive.
