2. Go to `Settings` -> `Controllers` -> `Controller Multitap`

## How to add texture packs?

`TITLEID` is different for every game.

You can either enable textures globally or per game.

**Globally for all games**

3. Enable `Load Textures` and `Async Texture Loading`.


### Add the texture packs to the correct folder

1. Extract any texture pack files from compressed `.zip` or any other compressed format.
2. Go into `~/retrodeck/texture_packs/PCSX2/`. 
3. Find the correct `TITLEID` that mactches your game.
4. Move textures into the right `~/retrodeck/texture_packs/PCSX2/<TITLEID>` folder.
5. If the textures match the game they should be loaded on next time you launch the game.
