RETROPIE PSP FOLDER ISNT THERE PATCH
There is one setting in PPSSPP, that can cause flickering, it is either in "lr-ppsspp" or "ppsspp", that was probably the last issue with "Ge Patch 2.0" on the vita, these projects are open source? (its suggested to reinstall PPSSPP from source, afterwards, I don't see a reason why though, since those bios files are not cached, unless I am mistaken) Replace all the 18 font files with the ones from your vita, this will fix PPSSPP Emulation on the Raspberry PI 4 home/pi/RetroPie/BIOS/PPSSPP/flash0/font/ ( (/forum/topic/24999/getting-the-best-psp-experience-on-a-pi-4/31)
Now to get PPSSPP working properly from the vita "font folder"
Take the entire "font" folder, to your PC.
