Question about retroarch


New member
I am using Retroarch for a number of systems, and all but one work for me
The one that is causing issues is ZX Spectrum
It will not let me enter the game.
The games say to press (1,2,3,4, etc etc ) from the keyboard.
However my controller (XBOX controller) will not let me program numbers.
So I am trying to add my Keyboard to retroarch as well, but i can not figure it out
Does anybody know how to make retroarch recognize a keyboard as well as a controller
Thank you.
