Retroarch controller mapping not saving

[Mikey123]

Hi all, when entering retroarch GUI to change controller mapping (need to change buttons for SF fba), the changes I make don't save, the button mapping is the same as before I made changes in GUI (I have saved and and set to save on exit). I have now also lost hot key function on pad :(

@Mikey123 You're not supposed to enable save_config_on_exit, that's not recommended. Instead, use the game/core remapping option to save your bindings per-game or per-core - see here. I'd reset the fba system's configuration file (/opt/retropie/configs/fba/retroarch.cfg) to the default one and start over.
The default contents of the file are

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

input_remapping_directory = "/opt/retropie/configs/fba/"

#include "/opt/retropie/configs/all/retroarch.cfg"

@mitu Thank you for your response, ive formatted and reinstalled everything:( All the videos showing core mapping are regarding old GUI, this was fine it's since the GUI mapping has updated that I can't get it to save.

@Mikey123 So.., right now do you still need help or have you figured out how the core remapping works ?
