@nadenislamarre Friend, after many searches on the internet I could not find the reason why the batocera does not save within the retroarch settings of the chosen shaders ... every time I restart the emulator I have to choose the shader again because I choose the option "apply shader setting ", The retroarch applies successfully, however, when you exit and re-enter the emulator the shader settings are not saved.
If I choose the option "save core override" the settings are saved, however, for some bug, the system disables the default controls (player 1, player 2) in the main menu ....
Could you tell me if there is any way around this problem?
Thank you for your attention.
