Memory cards are stored per game in the same folder as the game. Covers can be named as the iso/bin with .jpg (3264x3264 max) or .png (416x414 max) extension (or as COVER.JPG (3264x3264 max) when using PSXGAMES folder with game-name subfolder).

Don't forget that pressing [SQUARE] in the RETRO column groups content (emulator ROMS, PS1/PS2/PSP)."
