New to Launchbox and have quick question about Mesen

[Gamerdude420]

I am new to Launchbox, this program is amazing!!!  Thank you guys for making it.  

 

Just finished my NES library (tried all the games, deleted the ones that I don't want, never realized just the sheer number of horribly bad NES games LOL aside from what Angry Video Game Nerd would review LOL).  Anyway, I have been using Mesen standalone through this project, great emulator.  Standalone it starts fine and works great.  Launchbox, it goes to a game select screen, I disable the screen and star the game from power on (in settings), Mesen just sits there with a black screen.  I can exit it, but can't get past this part.  So I tried Retroarch, works great, the only problem is that once I changed the controller to act like a normal NES controller (switched from Xbox One controller to wired USB NES style controller), both B and A do the same thing (jumping) while B functions normally...had no controller issues in Mesen.  I would use Xbox one controller (as it functions just fine between B and A buttons, X and Y are turbo buttons, but I changed the exit from retroarch to the back button and can't figure out how to remove the mapping of that being the back button as I tried to just delete the mapping which only added delete as an exit hotkey).

This is the game select screen I was talking about in Mesen

A quick google found this, it needs the commandline in this thread.

Thank you, I tried the command line but it doesn't work.  I'm sure I'm missing something as I don't know much about using the command line in Windows.

Try:
/fullscren

None of this works at all with Mesen. Just black screen.
