MAME Exiting on P3's Up Key, But Isn't Mapped Anywhere

[kmustafa27]

Hey everyone, I hope this is the right area to post this, if not, please let me know and I'll happily move it. I'm having a bit of an issue I'm hoping someone might be able to guide me into fixing. What's going on is:

 

When I launch HyperSpin, and then select MAME and a game, whenever Player 3's joystick goes Up ('L'), the game exits and returns me back to HyperSpin's MAME wheel. However, if I launch MAME standalone, pushing P3's Up does not exit the emulator. So it only seems to occur when it's launched through HyperSpin.

 

I've checked MAME's keymappings, and 'L' is only mapped to P3's Up button, while 'C' and 'Esc' are mapped to UI Cancel. I've also checked HyperHQ's mappings, and only 'C' is set to exit. In RocketLauncher > General Settings > Controls, I've checked the Global and MAME settings, and nothing is entered in the "Exit Script Key" field. 

 

Has anyone seen this problem before, or have any idea where else to check to see what is causing this? I've posted this in the RocketLauncher forums as well. Thanks for any help!

 

[uPDATE] With help on the RL Forums, I was able to find the culprit - I missed the section in RLUI (Settings > Main Settings > Controls > Exit Emulator Key. All is good. Please close this thread. Thanks!
