Switch games should be put into the `retrodeck/roms/switch/` directory.
The games can come in many different formats: `XCI` `NSP` `NCA` `NSO` `NRO`. WIP ## Does Ryujinx require BIOS or Firmware? Needs the key files `prod.keys`, `title.keys` and the firmware files in the following directories: **Keys:** `~/retrodeck/bios/switch/keys` **Firmware:** `~/retrodeck/bios/switch/registered` The directory tree should look like this example: ``` ~/retrodeck/bios/switch ├── keys │   ├── prod.keys │   └── title.keys └── registered └── XXX amount of .nca files goes here ``` ### Install the firmware Ryujinx also requires the firmware to be installed via `Tools` -> `Install Firmware`
