Eg mirror L and R buttons to start and select buttons, while allowing start and select buttons to still be used for same purpose.
I greatly appreciate your reply.
I presume you are referencing Quick Menu > Controls?
If so, it seems remapping is limited to the number of buttons that core supports? e.g. GB / GBC supports 4 buttons, and so I can’t multi-assign start to L or R?
Are there any links you could point me to?
