[solved] How to change control mapping back ? Reset? Android app

Solved, found this info :

“press retropad start on the option to return to default. If you don’t have an external gamepad connected, you’ll need to go to settings > onscreen overlay and disable ‘hide overlay in menu’ or whatever it’s called so that it shows all the time. I personally like this better than using the regular touch menus anyway.”

Hello everyone,

I’ve tried looking around for this answer but no luck so far with this specific situation …

I have Android phone (moto x 1st gen) with RetroArch installed. Trying to play GBC game using Gambetta emu.

Under controls in quick menu, I pressed on “user 1 B” and it changed it… I kept pressing hoping it would cycle back around to default but it just stopped on what seems the last possibility… “retropad R3 button”

Then… to make matters worse I hit “save remap file” … overwriting the default file it seems…

So B button doesn’t work anymore…

How do I return it to “B”?

I tried deleting RetroArch and reinstalling but it didn’t reset this option!

Any help appreciated
