Patapon 3 AI upscaled (2021-05-28)

While replacing textures inside the ISO is doable, it's complicated to do it with upscaling. This is because upscaled images take a lot more space.

Even an old PC these days often has over 1024 MB of video memory. The PSP only has 2 MB.

When PPSSPP does texture replacement, the replaced textures aren't in the PSP's tiny memory. Instead, they are on your phone, laptop, desktop, etc. in its memory. So they can be very large and it's fine. Already, sometimes people have issues with heavy texture packs on weaker devices because the texture pack uses up all of their video memory - even when they have hundreds of times as much as the PSP.

The Vita only had 128 MB of VRAM and 512 MB of RAM - much less than most phones have. There's no easy way to access it from a PSP game either, so it'd be a lot of work and still might not be enough space.

So unfortunately - the answer is that it's pretty hard to get PPSSPP texture replacements on the Vita.
