Additional apps don't work after switching default emulator.

[dariodb]

I imported my arcade ROMs (merged 0.231) using the import MAME fullset option in Launchbox. Now I'm changing the default emulator for some playlists like CPS, CPS2 and so on. After changing the default emulator, alternate apps don't work anymore. I can launch the game as long as it's the default app, but launching alternate apps (like other regions or versions) doesn't work at all.

I also tried editing the game, going to Additional Apps, then selecting the one I want to launch by default and clicking Make Default but it results in the game not launching when double clicked.

For example, I have Alien VS Predator (CPS2). When I double click it the European version launches (avsp.zip), but when I try to load the American version by right clicking the game and selecting Play x Version... nothing happens. And when I change the default app by editing the game then the game won't load at all anymore when double clicked.

Note: alternate apps worked flawlessly before changing the default emulator for CPS2 to retroarch's CPS2 core.

Are alternate apps only supported when using MAME?

You can't change the default emulator for a playlist; that's not a thing, unless there's something massive that I'm missing. How are you changing the default emulator for a playlist?

Hey, Jason! Thank you so much for your reply! The way I was able to do this was going into a playlist, selecting all the games in that playlist, right click, Edit, and then changed the default emulator from there. If that's not the proper way to go about things then how should I do it? Basically my objective is to import a full MAME set and then setting the proper emulators according to platform (like CPS, CPSII, Naomi, Atomiswave, NeoGeo, etc).

Okay, I see. What are you changing the emulator to for those games? What emulator are you using?

So far I've tried Retroarch using the CPS and NeoGeo cores

Okay, so most likely your configuration of the Retroarch emulator in LaunchBox is the problem; either that or Retroarch itself. You need associated platforms for the platforms you're using in the Retroarch configuration:

Looks fine to me, can you spot any errors?

Arcade is blank there for the command line. What is the platform the games you're using? Not the playlist, but the platform. It's probably arcade, so that's probably the problem.

Because you have called the emulator CPS and not Retroarch, you are missing Retroarch specific settings like core dropdowns instead of hand typing that command line. That is likely the issue.

It was in fact Arcade, I've now switched it to Capcom Play System by selecting all the games in the playlist, right click, Edit, and changing the Platform from there.

Absolutely right! I've added Retroarch as a separate emulator, added Capcom Play System in the Associated Platforms and set it as default emulator for that platform.

Now when I try to launch an alternate app I get an error saying The ROM file you've specified does not exist. Main game still loads fine with proper emulator (retroarch cps core).
