I feel like I should know this, but I've been going through and redoing my LaunchBox setup to make it perfect. I've finally started dealing with the controller mapping and I was trying to swap between systems and games. Like jumping from SNES Super Mario World then jump to N64's Super Mario 64 as an example... and I can't figure out how to jump between the systems and games with just a controller.
I know I can use the mouse, but I'd really like to just use the controller, and I went into the controller mapping settings, and I couldn't figure out a setting for it. Is this just not able to be done? Seems like a pretty basic one that should be in there and I feel like I'm just probably not seeing it somewhere.
