|-- code/
|-- app.xml
|-- cos.xml
|-- rpx (executable file)
|-- content/
|-- (all game assets, sound, levels)
|-- meta/
|-- icon.png
|-- meta.xml
For Super Mario 3D World (USA version), the Title ID is 00050000-10145D00 (varies slightly by region). The Loadiine-compatible version will contain the decrypted, unpacked game files, not a single ISO image.
