Wonder if anyone else has had this issue since updating to the latest version of Launchbox/BigBox. Since i upgraded to the latest version when i try and load a ROM that uses a core in RetroArch the bezels appear but with a blank screen. If i click anywhere all i get is a windows error saying that RetroArch is not responding. If i load RetroArch up on it's own i can play all the games with no issues. The same happens when i use BigBox. Any ideas would be appreciated.
