Multi-Disc Games¶
Some video games for disc-based consoles, especially those with lots of cinematics, come on more than one disc. Once you added a multi-disc game to your KNULLI device, each disc of the game will show up as its own game. Of course, this adds unnecessary clutter to your game list. Therefore, KNULLI comes with a feature that allows you to hide all the discs of the multi-disc game and display a playlist instead.
All you have to do is create a m3u playlist file within the folder for the ROMs of the given system and add relative path references to all the disc images in the correct order.
If you feel unsure how to achieve that, follow this guide. It will take you through the process step by step.
Make sure that 'Ignore Multi-File Disk Content' is turned on
KNULLI comes with a setting that allows to hide or show the content (the individual discs) of multi-disc games. By default, hiding individual discs is turned on. However, if you have issues with individual discs unwantedly showing up on your Knulli device, make sure this feature is turned on.
Press Start to bring up the main menu, go to System Settings, then Frontend Developer Options, where you find the option Ignore Multi-File Disk Content (CUE/GDI/CCD/M3U). Make sure it is turned on. To apply any change you made here, you will need to update your gamelists by going to Game Settings from the main menu and select Update Gamelists.
This option will hide every disc file that is correctly referenced in a playlist. If your game discs still show up, there is likely something wrong with your m3u file.
How to store multi-disc game files¶
There are several possibilities how to store multi-disc game files. Let's take the PlayStation classic Metal Gear Solid as an example.
As thoroughly explained in the Add Games section, all your games have to be stored in your userdata/share folder in a subfolder of roms that corresponds to the system the game was developed for - in this case, psx, the folder for PlayStation games.
Top level of the system's ROMs folder¶
Some users prefer to add their multi-disc games to the ROMs folder like any other game:
Game-specific subfolder of the system's ROMs folder¶
Some users prefer to create a subfolder for every multi-disc game and drop all the files there:
"Hidden" subfolder of the system's ROMs folder¶
some users prefer to put all their multi-disc games in a subfolder called hidden (or something similar):
Creating the playlist¶
After you stored the files on your KNULLI device, you can now create a playlist to group all the discs that belong to a single game into a single file.
For that purpose, create a plain text file with the file extension .m3u. Ideally, the m3u file should be named like the game and its discs, so for the example given above, the file name should be Metal Gear Solid.m3u.
Following the above examples, you now have two options where to store the playlist file. You can either store it on the top level of the roms/psx folder or optionally in the same subfolder you might have stored your game files in. Depending on where your game files and your playlist file are stored and how they relate to each other, you now need to edit the playlist file:
Playlist and game files in the same folder¶
If you decided to store your game files and your playlist file in the same folder, make sure that your m3u refers to the game files directly without any path.
For the examples shown above, your Metal Gear Solid.m3u file should contain
if it is stored in the same folder as Metal Gear Solid (Disc 1).chd and Metal Gear Solid (Disc 1).chd.
Playlist and game files in different folders¶
If you decided to store your game files and your playlist file in different folders, make sure that your m3u includes the path when referring to the game files.
For the examples shown above, your Metal Gear Solid.m3u file should contain
if your Metal Gear Solid.m3u is stored in roms/psx and your game files are stored in roms/psx/Metal Gear Solid.
