@annomatik said in Custom Mega-Drive Controls:
So... I might have found a bug or maybe that's just the way it is. Apparently, RetroArch is only able to configure things in the remap , if they exist in the controller config? In other words "if the button 5 is not configured in the config, it will be only available in the current session, but not for the remap file"?
Kind of. It's not really button 5, but button who' s input code is 5. If the input code is not mapped to one of the RetroPad's buttons, then it's not available for remap.
If you modify your controller's .cfg file and add labels to the buttons (like I did), then you'll get rid of input codes and just see the button names in the control mapping menu - makes it easier to see which is which.
