Sorry to tag on a question, but I don't think I need to make a new thread for this. When I try to change the plug-in, it doesn't give me the option for using the keyboard plugin under default setting. It will let me if I choose 'Display ROM plugin setting', but it will say in brackets, 'unavailible'.
I can use the keyboard for some ROMs, but others tell you there's no controller plugged in right away, so I can't change it once I've opened a ROM.
Sorry if it's a bit confusing.
