I’ve imported lots of systems and all are working well except Arcade. I’ve imported Mame 2003 Plus romset but when I try to run a game I get a black screen. If I run the game from Retroarch directly, it works, is pattern is repeated of all the games I’ve tried. I’ve checked my setting and both the correct version of Retroarch and it’s core are selected in Launchbox. I’m running this on a NVidia shield, with the latest Launchbox.
