I can´t get newer versions of retroarch to work with mednafn psx. The newer plugin works for me but only in version 1.0.0.2. any newer version gives me a black screen. I don´t know if other people have the same problem as I searched the forum and only found problems related to missing bios. I turned on verbose log and this is how it ended in 1.2.2. if you need more info just ask me. I’m happy to do some more tests.
