Multi-disc Game Wont Launch from LaunchBox

[grim.]

I am able to play this 2-disc game on Retroarch's PPSSPP core from within the Retroarch interface launched separately, but when I double-click on the game in the LaunchBox menu, I get the loading mouse pointer for about 1 second before it reverts to a pointer and nothing happens.

Here are pictures showing:

1. the LaunchBox submenu where I tried to launch the game by clicking on both discs and nothing happened. I also tried "Open Retroarch" and the "Launch with..." options but I couldn't get the game nor Retroarch to launch.
2. the ROM file directory showing that the game is setup to launch Disc 1 by default
3. the Additional Apps tab showing that both discs are identified by LaunchBox as part of one game.

Also, I did enable "Use M3U Playlists for Multiple Discs" already.

Have you added PSP to the associated platforms tab for Retroarch, and if you have does the system name there match EXACTLY what you called it in Launchbox?

[grim.]

Yes and yes.

I remember I had to import the two discs in several different ways because LaunchBox kept adding them as two separate games even though it KNEW they were Disc 1 and 2. Maybe that was LaunchBox's way of telling me that they shouldn't be combined.

That core does not have m3u support.

Ugh. That's unfortunate. Is there a workaround or should I just re-import the games onto LaunchBox as separate games and just deal with it?
