# Yuzu

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


## Where do I put the BIOS files?
Yuzu needs the key files `prod.keys`, `title.keys` and the firmware files in the following directories:   
  
**Yuzu keys:** `~/retrodeck/bios/switch/keys`   

**Yuzu firmware:** `~/retrodeck/bios/switch/registered`

The directory tree should look like this example:
```
~/retrodeck/bios/switch
├── keys
│   ├── prod.keys
│   └── title.keys
└── registered
    ├── 02259fd41066eddbc64e0fdd217d9d2f.nca
    ├── 02582a2cd46cc226ce72c8a52504cd97.nca
    ├── 02b1dd519a6df4de1b11871851d328a1.nca
    ├── other 217 files...
    └── fd0d23003ea5602c24ac4e41101c16fd.nca
```

You can find a complete guide in the [Yuzu official wiki](https://yuzu-emu.org/help/quickstart/#downloading-and-installing-yuzu) on how to extract the BIOS from your Switch.
