[All emulators extremely laggy when launched via LaunchBox until I alt+tab out and back in]

sorry, but what emulators are we talking about ???

Any core I choose in RetroArch. Evidently something is causing the FPS to tank and it doesn't recover unless I alt+tab or even hit the Windows key. I dunno, I'm going to end up returning the machine anyway and look for something a little more powerful overall.

If I launch a rom directly from RetroArch I have no issues. However, when using LaunchBox when the roms load I have to hit alt+tab a couple of times and then the lag/stutter/crackling will go away and everything will run fine. I don't understand this at all. It's a weak system (j4125) and LaunchBox is very slow in general, but the emulators themselves run fine unless I launch them through LB.  

[Possible to automatically bind controls to all MAME games?]

Would like to be able to bind "select" on my controller as Coin 1 in all my MAME roms. Possible? Or do you have to configure each "machine" individually? 

edit: Found it under Configure Options, General Inputs, Other Controls.
