This doesn't appear to be any kind of game compatibilty report, softm - you haven't given the name of a game or made any useful comments on how it runs, And there's certainly no 7502 version of pSX: that's the number usually used for a PAL BIOS.
<sigh> I'll move this to Chat. Please try to post more appropriately in future.
Edit: I think I understand - vaguely... you're reporting on something played on an actual Playstation. This is not a Playstation support forum, it's the pSX Emulator forum. Game Compatibility is for coherent reports for games played in pSX Emulator.
Moved to Chat - patrickp

So what you are saying is that the real PlayStation does very accurate g-shade dithering? Isn't it like supposed to?

Great photo evidence there.
I know someone around here hooks his Playstation up to his PC via a capture card. Maybe if he sees this thread he will provide better photos of the same thing.
;D

I didn't even noticed anything diferent between the images, but if its better in pSX than the real console, its a good thing, right? Its like the slowdowns that happens on the real console but don't happen on pSX: I for one would hate if pSX emulated the slowdowns.

Of course, running a Playstation into a PC means you can do screenshots, of course - and because you're using essentially the same output path as pSX does, it gives you a much better comparison. I didn't even noticed anything diferent between the images... Me neither. Considering one is (presumably) a detail from a screen shot, and the other is a photograph of the image on a TV, I'd say the differences between the media probably account for more difference than that between the images.

SOF: You may need to turn on the macro mode of the camera to get a better picture of small details like that on the screen. The other option would be, if you're using a landscape option (which tries to keep everything in view focused), make sure that you're straight on facing the TV, and that the picture contains *only* the TV (to eliminate different depths as much as possible). Either that, or if you can control where your camera focuses, still face the screen straight-on, but make sure that the center of the area being used as the example is centered within the area being focused upon. And I think I see the difference you're talking about. Looking at the two pics, I see that in the pic from the TV, the colours don't mix together as well. Like... take each picture, and look at them as containing lines. In the pSX pic, the lines of solid-looking coloured pixels are about as wide as the ones containing different coloured pixels. But in the pic with the real PS1 on a TV... the lines of multi-coloured pixels are wider, with the solid-looking lines being much thinner.

pSX uses one less bit of accuracy than the real hardware when doing dithering for performance reasons (32 is nicely divisible by 2, but not 3 . Most of the time this isn't noticable but you can see it on clean gradients like that - I may change this in the future (possibly I could make it optional).

Interesting. Sounds like something that would up the minimum requirements quite a bit. Good to see you around again by the way. patrickMaybe you can find another game in your collection that dithers the graphics in the same way. Would be nice to see some high quality screenshots of the difference between pSX and a real PlayStation. I think Silent Hill would be a worthy candidate, if you have that.

I think I recall Final Fantasy Tactics having gradients as the battle field backgrounds. Whether that's a good game to try to spot the difference, that I don't know.

No, I don't have Silent Hill or Final Fantasy Tactics. Any other ideas?
