Exiting Mame in Launchbox

[FakedPotato]

I have not had any success with retroarch using my mame set. I decided to use my stand alone MAMEUI emulator that runs my whole set fine, but havent found a way to exit mame properly.

When mapping my button on the controller to B for exit, i exit the game as Im playing and pressing B, so im not sure where to go from here! Kinda lost.

Set your exit key in Mame back to Escape and if you are using the premium version of Launchbox set your controller button combo in the controller automation section of the options (have to set it in both Launchbox and BigBox) and it will just work by default since the controller automation is set to Escape.
