CHD & 3MU clarification

[OldSkool8bit]

So quick clarifying question as I have seen conflicting information. I know I can use a 3mu file for games with multiple iso disks....but what about chd's? I have a few systems where some games have multiple chd's for them and my ocd only wants one icon in launchbox for the game. Can I follow the same procedures and create a single source (of multiple chd disks) using chd's and 1 3mu?

Yes it's .m3u, just follow the same logic as with .cue, basically you can just modify your existing .m3u files and replace all the .cue with .chd once you have converted your files to chd.

Here's an example attached anyways.

Final Fantasy IX (USA).m3u

Import all the ISO or CHD files, check the "Combine games with same title" box in the import, in the emulator make sure the Create a m3u checkbox is checked, then play your games. LaunchBox will make the m3u for you.
