Sorry if this is easy or been asked before, I spent hours and cannot find a recent answer to this question. I mostly use Retroarch for Neo Geo games. I cannot find a way to make buttons like AB, CD, ABC, etc to bind to 1 controller button. I see screenshots of Quick Menus with this option but everyone refers to lr_fbaphla. My Retroarch does not have that, I have tried every FBA and FBNeo core and they are all the same when in Quick Menu. How do I assign these buttons or do I need to find an old build with old cores that support it?
Thanks in advance!
