This seems to exclusively be ps1 titles. This came on suddenly and was working previously. I have deleted and reinstalled the games, and have check individual game paths to be sure they were correct. Games will play via Duckstation outside of LB and BB, but not in it. I have tried retroarch versions inside LB as well, with the same results. Perhaps I'm missing something obvious. I have even tried importing one game at a time, checked the path and tried both emus within LB- same results.
