[Multiple instances of Mame starting]

When I select a game through Big Box on my arcade cabinet, sometimes a few instances of Mame will open at the same time. Is there a Launchbox way to prevent this? I'm using Mameui64 and cannot see an option to prevent multiple instances.

[Invalid user/password combination from Retro Achievements]

I figured out the problem. While I did re-enter the password in the RetroArch app, I also had to add the password manually to each RetroArch .cfg file I have. Like RetroArch.cfg, NES.cfg, SNES.cfg, ect. I also had to remove the chevos_tolken from each of the .cfg files and then all games launched from Launchbox logged into Retro Achievements. 

Will I have to do this everytime I update either Launchbox or RetroArch? This is going in an arcade cabinet, so that might get pretty annoying.

Believe that is a known issue with older RetroArch installs. I had that happening for a while but it stopped when I upgraded.

I just updated RetroArch, but now I get a different error: "no password provided for RetroAchievements account"

There is nowhere to put a password for it in LaunchBox. I login fine if I launch games through RetroArch tho. What is Launchbox doing differently to get the error?

[Invalid user/password combination from Retro Achievements]

When launching a RetroArch game from Launchbox, I get the "invalid user/password combination" error. I have reset my api and put the new key in Launchbox and I still get the error. Even after pressing "Test" and successfully connecting from settings.

When launching a game from RetroArch, I log into Retro Achievements just fine.

Any ideas?
