Hi, new LaunchBox premium user, love the way you can set this up to run so many emulators from just a controller. I'm using retroarch for as many systems as possible including MAME - I'm using an xbox 360 controller and have successfully setup hotkeys to exit the emualtor and save/load states (for all my retroarch cores) but I'm having an issue with a MAME specific hotkey that I can't change.
Basically, the Left thumstick button is auto set to open the arcade diagnostics function - which obviously resets any game you're playing - it's quite an easy button to press by mistake and I keep losing game progress and can't for the life of me figure out to change or disable it. If anyone could help me that would be great.
