Games load normally in Retroarch but won't launch in LB

[Xerosting]

I've been trying to find the answer to this and kind just keep getting the runaround with the answers I'm finding. For most systems that use Retroarch, a game won't do anything when trying to launch in Launchbox but it will load normally in Retroarch. I've verified the correct cores are installed, tried different cores, even tried downloading the direct emulator to bypass Retroarch while making all the proper changes in the Associated Devices tab, but have had no luck. The STRANGEST thing is that Super Nintendo using the SNES9X core works perfectly, but Sega Genesis (and all it's variants) using PicoDrive or GensPlus, Dreamcast using Flycast, NES using Mesen, and many others just don't seem to work. I feel like I'm probably just missing something small but does anyone have any ideas?

In addition, this might be a simple fix as well but I can launch Wii games pointed to Dolphin, but for GameCube it tells me it can't use the .rvz files even though they load fine in the Dolphin emulator directly. Is there some kind of pass-through that needs to be checked somewhere to just tell it to play?

To help determine what's going on, in LaunchBox can you share some screenshots:

- edit your emulator (in LaunchBox) and share a screenshot of
     - the Details section
     - and the Associated Platforms section.
- edit [just] one of the games not launching from LB and share a screenshot of
     - Launching section

Omg, I just figured it out since you mentioned the Launching section. It seems on import, LB put a ._ before every one of my roms causing it not to find the game. Once I edited one in a couple of different systems, it loaded normally. Gonna try to re-import to not have to change each game individually but thank you for the suggestion!

Looks like this also resolved my Gamecube issue. Seems importing the folder added the ._ before each file name but selecting the entire file list to import instead resolves this.

Sounds like a Apple/Macintosh file naming convention.
