Textures loading problem

Keep in mind that a 4K texture pack means textures are 8x the size on each side. Additionally, replaced textures are always 32-bit color. That means a single original pixel which would've required 2 bytes now requires 256 bytes.

So if normally emulating a game might require say ~100 MB of VRAM, it would now require 12 GB of VRAM with a 4K texture pack.

When we try to load a texture and you're out of VRAM, graphics drivers don't always handle this well. PPSSPP may crash, but in most cases it'll just result in a black texture. That's what causes the black.

Your operating system will most likely first try to swap RAM or even VRAM to disk, which will tank performance fast. You do not want to run out of VRAM. If you want to use 4K texture packs, you'd better have a video card with tons of VRAM like the NVIDIA GTX 2080 Ti.

You can use a tool like GPU-Z to monitor your GPU's load and VRAM usage to get a sense for whether this is a problem you're experiencing.

JPCSP hasn't run all the games I like well, but if it works well for you - great. I'm glad you've found a solution.

But just to maybe state the obvious - I don't know much about JPCSP's texture replacement feature, but I'm pretty sure it doesn't use the same hashes as PPSSPP does if it has such a feature. PPSSPP's hashes are based on a seed value that is just a number we made up. If you're trying to just use a JPCSP texture pack with PPSSPP, it obviously won't work.

jpcsp works pretty well is just a matter of knowledge on how the games works only and making the settings besides that is easy has a 95% of compatibility and is the only one running MH3 portable (the original) out of the box and God Eater 1.01 which ppsspp still won't run in fact there are games that work better on jpcsp in fact the only reason i use ppsspp is because doesn't have high requirements compared to jpcsp but if i take your words for granted on how ppsspp works then is behind jpcsp in requirements since that will load 4k without higher requirements so it seems ppsspp is having some serious issues (as always and reason of people not wanting to update)

And it seems you still don't understand how it should work texture replacing if the name is random and not a real name or game hash obviously will never work because is not something real from the game this is why i asked "Has this feature worked before" because taking for example jpcsp it will extract the original texture of the game and will make the procedure
.- check if there is a texture replacement for file XXXX.png
.- there is a replacement for file XXXX.png load said file instead of original
.- if not load default textures
Reason of why has higher requirements on certain points.
Normally random hash are troublesome and this feature had several problems after seeing the comments and never worked as intended since will generate 2 to 100 random hashes for same file texture so does this work or not.

Normally i'm against this but i want you to make a video of dumping the texture,editing said texture,and loading the game with the texture replaced either vulkan opengl or whatever backend without interruptions to prove your point and that it works, since this feature has never worked in the past after checking comments

What versions of ppsspp i tested well almost every version since the launched this feature and none worked only exceptions would be the crippled ones which i jumped (those that have inferior performance and made on purpose that way since gold version of the same worked better)
