This is where you specify the location for all your BIOS's, by default RetroArch looks for BIOS in your 'Starting directory' folder. Some distributions use ~/.config/retroarch/cores/ libretro_directory = is what you need to change in the config file.
If you want to change it manually, you might want to change this directory from 'retroarch.cfg' with a text editor since the RetroArch file browser doesn't show hidden folders by default. The Ubuntu PPA does not point this to a user-writable directory because cores are modified by the package manager. To install them using the user interface, this setting needs to point to a writeable directory. If all hope is lost do a system-wide search for retroarch.cfg If you are having trouble locating your retroarch config folder, check back in the Directories setting, take a mental note of what appears on the Config directory, this should lead you to a retroarch folder.
Select the directory you want to changed.Next step you might want to consider is setting directories for RetroArch, this can help get the best experience possible.Īlthough the defaults will suit most users, if you want to configure custom BIOS's or change the save location, you will have to change directories.
