Hi, I followed a youtube tutorial to install launchbox and some N64 Rom files. All the games were scraped and added to the folder but now all I see is the main screen that launches when a game starts up and it says configuration override loaded, then the screen crashes and no error messages or anything pop up. What did I do wrong? I even tried going into retroarch online updater and downloaded the core for the parallel N64 and the other one. When I reboot I don't get the option to use the parallel core that I downloaded either. I think it said something about failing to save a config file the first time I tried it. Thank-you for your help.
