The original PSP hardware rendered games at a low resolution of 480x272 pixels. When you upscale the internal resolution in PPSSPP, the 3D polygons become sharp, but the 2D textures (like user interfaces, character faces, and environmental details) remain muddy.

Boot up the game in PPSSPP, pause it, and look at the top window bar or pause menu info. Ensure your folder name in the TEXTURES directory matches that exact alphanumeric code.

Set to 16x . This makes ground textures look sharp even when viewed at a distance or a flat angle.
