Adding Texture Packs

The ~/retrodeck/texture_packs/ppsspp-sa/ folder represents the /PSP/TEXTURES/ folder in PPSSPP.

Note:
Some texture packs may be made for a specific version or region of the game. Make sure you have the correct ROM and textures for it.

SERIAL is different for every game. It's a unique code for each released game per region.

Example:

SERIAL: ULUS-10080 corresponds to the NTSC-U release of 007-From Russia with Love.

You can search various databases or wikis online to find the correct serial for the version of the game you have for example:

Enable Custom Textures

  1. Open PPSSPP inside RetroDECK Configurator by pressing Open Emulator → PPSSPP.
  2. Go to Settings → Tools → Developer Tools → Replace Textures and set it to On.

How to Add Texture Packs

  1. Extract the texture pack files from compressed .zip or other formats into folders.
  2. Navigate to retrodeck/texture_packs/PPSSPP-SA/. The folders are named by SERIAL.
  3. Paste the textures into the correct folder: retrodeck/texture_packs/PPSSPP-SA/<SERIAL>
  4. If the textures match the game, they should load the next time you launch it.
