I´ve had a big problem and cant find any help on google and other forums.
I´ve searrched now for two days and cant fix it!
Every time I start a retroarch emulator (it doesnt matter if I use SNES or PSP etc.) I got the following error:
Failed saving config to “/opt/retropie/configs/*****/retroarch.cfg”
(***** = retroarch core)
I also got this error if I start “Configure Retroarch /Launcch Retroarch Rgui” in the emulationstation menu:
Failed saving config to “/opt/retropie/configs/all/retroarch.cfg”
I´ve made a fresh img install of retropie 3.6 rpi2 on sd for my rpi3.
Then I´ve reinstalled bluetooth to fixed the problem with my ps3 controller.
I have not changed anything else on retropie.
