"PS1 Emulation can do amazing things nowadays (FFVII)

We've all seen those crazy Dolphin/Cemu screenshots running Nintendo games with great art direction even at 8K internal resolution with ridiculous image quality. Anyone who has delved into tinker with emulation has quickly ran into an issue, however: many old PS1 games look utterly awful when running on higher resolutions! Specifically, most classic Square RPGs including the Final Fantasy games have pre-rendered 2D backgrounds with 3D models on top. Running these games at a higher resolution generally results in a severe mis-match between the soft hand-drawn backgrounds and the razor sharp 3D models that don't even look very good to begin with.

Well, what if I told you that there is a much better way to render PS1 games on modern hardware? Enter RetroArch with the Bettle PSX HW Core. I've included a video I threw together quickly in order to explain a few key settings, but the gist of it is that you can now render the 3D models at whatever super high resolution you want and then downsample them back to the original PSX resolution. The results are staggering. The 3D models suddenly look just as hand-painted as the backgrounds and blend together perfectly. Also on display are the battles running at a much higher framerate than the original 15 fps due to internal chip overclocking. In FFVII (un?)fortunately results in the animations/movement also running a lot faster, making this a turbo mode of sorts. If it's your first time playing probably stay away from those settings, but for those of us who have cleared the game many times it might actually be a welcome addition, bugs and minor issues notwithstanding.

Keep in mind that Youtube compression ruins CRT filters. That particular aspects looks much better in person. Anyway, here's the video:

It goes into more detail on specific settings and shows off how the game looks if anyone is interested in trying this out for themselves. Personally, I've been enjoying these games more than ever thanks to this for a few months now and figured I would share my experience. Cheers!"

Interesting.  Though the CRT filter helps hide the low resolution of the original backgrounds, it also helps hide what improvement was gained from this method

My own crt with upscaled backgrounds is even better:

I went ahead and used the same method, but without a CRT shader, to more clearly show what this technique is actually doing to the image. The first half of the video uses the "Pixellate" shader, which is basically nearest neighbor without the rounding errors, and the second half has no shader at all and is basically straight bilinear upscaling.

I think I could get used to playing the game with supersampling and a CRT shader, but if I did, I would definitely do some gamma compensation; the video linked by sen is just too dark.
