Title Directories

Authoring full retail title directories with conforming metadata, icons, and keystones.

When deploying an application to run as a full-screen retail game (BIG_APP), the console's application manager requires a structured directory layout containing specific metadata files.

Recipe: Generate a Retail Title Directory

selfish --input build/gl-cube.elf \
        --target prospero \
        --format title \
        --title-id GLCB00001 \
        --category big-app \
        --name "GL-Cube 3D Demo" \
        --output build/title/GLCB00001

Generated Layout

build/title/GLCB00001/
├── eboot.bin                <- Signed executable container
├── sce_module/
│   └── libc.prx             <- Companion runtime module
└── sce_sys/
    ├── param.json           <- Conforming metadata (titleId, category: 0, appVersion)
    ├── icon0.png            <- Conforming 512x512 RGB application icon
    ├── keystone             <- Fake-signed keystone paired with generated passcode
    ├── nptitle.dat          <- Network title identifier token
    └── pfs-version.dat      <- PFS filesystem version stamp

Key Metadata Fields Synthesized

  1. param.json:
    • titleId: Matches --title-id (e.g. GLCB00001).
    • category: 0 for BIG_APP (retail full-screen foreground application).
    • localizedParameters: Contains application name shown on console dashboard.
  2. keystone: Cryptographic passcode binder used by the console to pair game save files.
  3. icon0.png: Standard 512×512 PNG icon displayed on the home-screen dashboard.
