So i just purchased launchbox the other day and am very pleased with it! That being said I have 2 questions I searched for but didnt find an answer. I use a dualshock 4 for all my games I have. It works in most except MAME. I wont let me even configure it. Also, I would like, if possible, to have to DS4 wake the PC after I sleep it in BigBox, is that possible? thanks in advance
