Multidisk/File Games: Folders Interpreted as Files

To keep your game list clean, you can put all the game files inside a sub-folder. This folder will be seen as the game itself in RetroDECK, not as an actual folder. The folder needs to have the corresponding .m3u file and be renamed to the exact filename of the .m3u.

For more information, you can check the: ES-DE UserGuide: Folders as Files.

Guide - How do I create a Multidisk Folder?

Let's use the fake PlayStation 1 game Dragon Fantasy VII as an example.

Example:

โ”€โ”€โ”€ Dragon Fantasy VII.m3u   <--- Folder
    โ”œโ”€โ”€ Dragon Fantasy VII - Disk1.chd <--- Game Disc
    โ”œโ”€โ”€ Dragon Fantasy VII - Disk2.chd <--- Game Disc
    โ”œโ”€โ”€ Dragon Fantasy VII - Disk3.chd <--- Game Disc
    โ””โ”€โ”€ Dragon Fantasy VII.m3u <--- The .m3u file
In this case the folder will be viewed as a single game and it will launch Dragon Fantasy VII.m3u.

Step 1: Create a .m3u Sub-folder

Make a new sub-folder in roms/psx (or whichever system you are creating for) and move the Dragon Fantasy VII files there. Name the folder Dragon Fantasy VII.m3u.

Result:

Path: retrodeck/roms/psx/Dragon Fantasy VII.m3u

Content:

โ”€โ”€โ”€ Dragon Fantasy VII.m3u   <--- Folder
    โ”œโ”€โ”€ Dragon Fantasy VII - Disk1.chd <--- Game Disc
    โ”œโ”€โ”€ Dragon Fantasy VII - Disk2.chd <--- Game Disc
    โ””โ”€โ”€ Dragon Fantasy VII - Disk3.chd <--- Game Disc

Step 2: Create a .m3u File in the Sub-folder

Create an empty file in the Dragon Fantasy VII.m3u folder with the same name as the folder: Dragon Fantasy VII.m3u.

Result:

retrodeck/roms/psx/Dragon Fantasy VII.m3u/Dragon Fantasy VII.m3u

Step 3: Populate the .m3u File

Open the Dragon Fantasy VII.m3u file with a text editor and write the filenames of all files in the folder, one per line and save.

Result:

This shows the content of theDragon Fantasy VII.m3u file:

Dragon Fantasy VII - Disk1.chd
Dragon Fantasy VII - Disk2.chd
Dragon Fantasy VII - Disk3.chd

Step 4: Launch RetroDECK

The ES-DE interface that RetroDECK uses should now recognize the game as one file.
