Hello , i have more problems GTA games , Vice City , Burnout dominator and some other i think the most recent PSP games boots fine and menus are ok.
But in the game the graphics are broken and unplayable. Cars and people falling trough the road and grass etc.
Same roms / dvd content are fine on ppsspp win10 desktop machine.
Tried vulkan on the PI4 but more and the same problems, also tried booting retropie standalone image and on twister os same result.
PI4 / 8GB

ppsspp without retropie same problem.
