On both PCSXR and Mednafen I can't use the OpenGL to play my PS1 games. I have to use SDL, and the graphic sucks.
I have googled this a lot. Follow all that steps to delete the emulator files, modify some parameters and this kind of think. I have libgl1-mesa-dev instaled.
I'm using Debian 9.
Here are the log of Mednafen:
