Yuzu was a Switch emulator.

**Note: Archived Emulator**

It was removed as part of the `0.8.0b` update.

The last version that shipped with Yuzu was `0.7.6b`.

## Where to put the games?

Switch games should be put into the `retrodeck/roms/switch/` directory.

## What file formats are supported?

| File Format | Description |
|-------------|-------------|
| .xci        | Nintendo Switch Cartridge Image |
| .nsp        | Nintendo Submission Package **(Recommended)** |

## Does Yuzu require BIOS or Firmware?

Yes, `prod.keys` `title.keys` and `.nca` files.

### Where to put the firmware files?

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
```
