# Downloads playlists from "balb" user to be used in RetroArch under native
# installation for Linux. It will download all playlists, convert internal
# paths, change the filename and move it to the playlists folder. You have to
# set all three "_dir" variables below, as the default values are only my
# personal setup.


### YOUR SETTINGS

# Update the path to the main roms directory in the .lpl file.
roms_dir="~/Emulatoren/games/"

# Update the path to the cores directory in the .lpl file.
cores_dir="~/.config/retroarch/cores/"

# Destination folder for playlists files of your RetroArch installation.
# Created .lpl files will be copied to this place.
playlists_dir="~/.config/retroarch/playlists/"

### END OF YOUR SETTINGS
