They are PNGs. Are you clicking on the picture again after it's loaded on the PostImage page?

Anyway, after much playing around, I appear to have found a workaround of sorts.

While it's not a direct solution to the output/scaling problem, as it transpires it's okay for me to use bilinear filtering provided I combine it with a shader designed to maintain pixel sharpness.

With Kega Fusion I can use Double/DoubleRaw or Quad/QuadRaw from the plugins pack to eliminate blurriness and pixel misplacement, and some of the included shaders in the Windows archives of RetroArch for a similar result (such as Stock, Sharp Bilinear or Quilez). (With the latter though, I need to be wary about using a scale factor of 5x - while it makes the screen look just as crisp as it did with bilinearing disabled, certain cores take a significant performance hit with 5x, and may possibly result in a small reduction of FPS in all other cores.)

Or with Mednafen, there's a built-in setting to apply a sharper version of bilinear without the need for an external shader.

Well, here's what a typical Intel Options window looks like on my end.



Under the native resolution, those two scaling options are the only ones available. If I'm on a lower non-native resolution on the other hand, it unlocks a couple more options relating to aspect ratio (for instance, whether to stretch a 640x480 display or keep it at its original aspect).

Other than this, I'm not quite sure what else would relate to GPU scaling. Do integrated graphics have a GPU even? (I'm probably at risk of sounding like a moron here.)

"Produced big pixelated"? Not sure if I quite get you. :S

No, like I said I set fullscreen resolution to 1920x1080, matching my desktop. I just have "Fixed Aspect (Fit)" enabled in the options to get the proper aspect ratio (for the record, it's no better when stretched to fill the whole screen - still misplaced pixels).

I prefer to not use different resolutions as the long wait time for the monitor to spring back to life after each resolution change is aggravating enough.

Problem is, if you're intending to convert your game to EBOOT format afterwards, you need to find a conversion tool that's capable of handling external audio files, as well as one that understands ATRAC3.

I too had been hoping more research and work would be done on the newer PSX EBOOT formats with the compressed audio, but I'd imagine that most people have lost interest because "PSP iz old lolz" and they tend to just play the games on their Android devices these days.

Just bumping this since it's been over a year now and I don't think anyone's really thought to look into this, nor do I see solutions elsewhere on the web.

Anyone still interested in dissecting the format? The Mediafire link in my initial post still works, quite surprisingly.
