Hmm, the prim you have is a clear. Any breakpoint hits on that memory? -[Unknown]

It looks like that dmac memcpy should be copying between the two framebuffers. I wonder why it's not doing it though? sceDmacMemcpy should work. In Core/HLE/sceDmac.cpp, what if you take...

I don't know a ton about Retropie, but if you can try compiling a version at or getting an old version at v1.11.2-550-gdbe665880, that might help confirm if the issue...

I'm not sure if this is somehow libretro specific. None of the recent changes have specifically targeted this. I unfortunately have no idea how to compile retropie to walk you...

In that case, these are the compile instructions: https://github.com/hrydgard/ppsspp/wiki/Build-instructions#download-the-source-code https://github.com/hrydgard/ppsspp/wiki/Build-instructions#building-for-raspberry-pi-os-64-bit So basically you run these commands: ```sh git clone --recurse-submodules https://github.com/hrydgard/ppsspp.git cd ppsspp sudo apt install clang cmake libgl1-mesa-dev libsdl2-dev...

The screenshot seems to only show a clone, I don't see any build having happened. Try running the first set of commands starting from `cd ppsspp`. The clone can be...

Hm, is anything running on the pi? It seems like it couldn't get EGL running. This could be because something else is already using the screen, but I'm not sure....

It's definitely useful to know that didn't fix it, although I'm now not sure what could be the cause. -[Unknown]

Based on that, the likely range of commits is: https://github.com/hrydgard/ppsspp/compare/8c72cc119ee2f1a65d5524276eadd4dbdd838dbb...89ea9625a5cbe9e42cf4db327b085ec98787eae8 If you have a chance to test this version, knowing whether it works or not would cut the possible causes...

It looks like you may need to run `cd ppsspp` first. As for retropie, I'm not exactly sure how it works or where it expects ppsspp. Based on this script:...
