When I try to launch an arcade game from Launchbox or Big Box it looks like it's loading then nothing happens. In desktop mode on Launchbox if I go to tools > emulators > retroarch (only one on the list) > available platforms it shows mame_libretro - which is what I have downloaded in retroarch. I've tried all the other mame versions in retroarch, same result All of my arcade games work if I manually go into retroarch and load content Any ideas?! I've spent quite a bit of time on this to no avail. It's gotta be something IN Launchbox, right? Since it's working in Retroarch.
