## Specific system information

### Multi-disc

You can use a m3u file to manage multi-disc games.

For example for *Alone In The Dark*, if the ROM contains the following files:

<div align="left"><figure><img src="https://i.imgur.com/LUmmLpf.png" alt=""><figcaption></figcaption></figure></div>

create a `Alone in the dark The new nightmare.m3u` text file with the following content and save it to the /roms/dreamcast folder:

<div align="left"><figure><img src="https://i.imgur.com/9dQJhD9.png" alt=""><figcaption></figcaption></figure></div>

Retrobat will automatically detect the m3u file and hide the individual .gdi files from the Game List.

### Custom textures

Custom textures can be used with the flycast core.

The texture pack must be placed in the `\bios\dc\textures\` folder:

Then, enable **CUSTOM TEXTURES** in **ADVANCED SYSTEM OPTIONS** or in **ADVANCED GAME OPTIONS**.
