Retroarch Input Bind Config

[stevedee78]

Raspberry Pi B+, Xin Mo Dual controller

I'm new to retropie, and trying to work out how the various configuration files and options are layered between retropie and retroarch etc.

When I launch a SNES game currently, a few of the buttons are not configured as I'd like, so I jump into the Retroarch menu, go to Main Menu>Settings>Input>Input User 1 Binds update the missing buttons, then the same for Input User 2 Binds. If I then go to Main Menu>Configurations>Save Current Configuration I get 'failed saving config to "opt/retropie/configs/snes/retroarch.cfg"'

I have tried playing with permissions and setting the whole of the configs file structure to pi:pi or root with no change. I've tried deleting the retroarch.cfg that is already in that directory and still no joy.

Am I misunderstanding how to reconfigure the controls in the first place? Is this a permissions problem, or do I need to manually update the config file, or another config file?

Any help gratefully recieved thanks

You should use the Core input remapping in RetroArch to change the input bindings and not use 'Save Configuration' from RetroArch.

For the config file saving - could be a permission problem, check the permissions on the folder and file. The files in /opt/retropie/configs should be writable by the pi user, unless you've mis-used sudo and changed them.

@mitu thanks for the reply, just after posting it worked actually. So what I did was:

1. Deleted the tetrarch.cfg file that was in /opt/retropie/configs/snes (when I looked in there it was very light, couple of lines, mostly comments)
2. Launched Street Fighter II, then launched RetroArch within the game and configured the buttons in Main Menu > Settings > Input (both Input.1 and Input 2
3. Exit Retro Arch menu (think I clicked save Current Configuration too, but it still errors)

Then I noticed that it had generated a new tetrarch.cfg in that snes directory, much bigger than the previous one and full of config goodness. Exited the game, and now when I go back in the button configs are retained.

Think that the tetrarch.cfg that was in the snes directory was maybe corrupt, so it was ignoring that and deferring to a higher config somewhere else...works now though. Thanks for the reply

Yes, this is the default configuration - it's normal.

We don't recommend using 'Save Configuration', core remapping is the preferred method.
