Can not save hotkey input bind on retroarch 1.7.1 on snes classic

Hi,

I have Retroarch 1.7.1 running on an snes classic with a USB-HOST flash drive connected. I am using snes2016 as my core.

I used syndrome’s guide : https://www.youtube.com/watch?v=rx-Nl3NRw0Q

The problem is I am trying bind the rewind function to a certain button on the controller. I am able to do that and the rewind feature works fine, but if I exit out of retroarch or change games the bind automatically reverts back to “r” instead of what I set it to. The system will not save my hotkey bind for rewind at all.

Some help would be much appreciated as this has been driving me crazy for a week.
