Problem launching arcade games using Retroarch's FBNeo core

[drorin]

Hi! First of all, sorry for my english. Well, everything worked fine until I updated RetroArch cores or the new version of LaunchBox, or at least I realized after doing it. The problem is if I launch an arcade rom from RetroArch using FBNeo core, I have no troubles, but if I try to launch the same rom using LaunchBox linked to RetroArch with the same core the game doesn't launch. I get this message instead: "this romset is known but yours doesn't match this emulator and its version". I repeat, if I launch the same rom in RetroArch, this problem doesn't occur.

I don't know what happened to my LaunchBox or if it is a common problem, but I didnt find any solution by googling.

Greetings.

I'm having this same issue.  Is there a fix?  Launchbox and Retroarch are up to date, as well as fbneo core.

@thykingviking, you may need to uncheck "Extract ROM archives before running"

It's under Tools > Manage > Emulators, and edit your RetroArch emulator that controls FBNeo.

It is already unchecked unfortunately.  I do appreciate the help though!

Does the game run directly in Retroarch without using LB? RA is telling you there is an issue, not LB.

That's a error cause your romset doesn't match the version the core is expecting, that game obviously had a file change at some point and that file isn't in your different version romset.

Yes it runs fine in retroarch without LB.

Honestly its not that big of a deal.  They play fine in MAME from LB. I can just manually open those select games in FBNeo in Retroarch that are compatible with RetroAchievements.

Fixed!  I removed the full mame set, re-imported the full set to MAME/roms folder, (where they were originally) and now for some reason I can load them in LB through Retroarch FBNeo!  Everything is where it was originally.  So if you find yourself having the same issue, I would start with that, remembering to not delete your media files.

FBA doesnt use a MAME romset, it uses it's own FBA romset, so you may well run into a ton of games that do not work cause they are not designed for FBA.

Correct, but those that are, that I had previously tested that did not work are now working.  As I said, I just wanted those that are retroachievement capable to load from LB/FBNeo, and for some reason they are now.  I'm not going to question it.  Happy Camper.
