I'm using a Samsung phone with Android 13, and am trying for the first time to get LaunchBox working with arcade games. I bought the paid version of launchbox for both Windows and Android. I exported my games from Windows to a usb flash drive, and imported them to Launchbox on Android directly from the flash drive. I also installed Retroarch 64 directly from the Retroarch Build. I've tried the stable and nightly builds of Retroarch 64, but every time I try to launch a game on Android, Retroarch just comes up with a black screen. To try tracking this down, I tried to load the contect directly in Retroarch, but Retroarch apparently can't see the directory for my usb drive, which is located at /mnt/media_rw/XXXX-XXXX/Launchbox Any ideas on what I can to do fix this or track down what is going wrong? Thanks!
