## Where to put the games?
Switch games should be put into the `retrodeck/roms/switch/` directory.
The games can come in many different formats: `XCI` `NSP` `NCA` `NSO` `NRO`.

## 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`
