Let me start off by saying that I am an amateur at this. But I have been proceeding carefully, reading and searching the forums for answers, and really had a mostly flawless experience so far.
Long story made short: In my final steps of setting up, RetroArch was updated and now is asking for “clockwork pi login:” followed by a password.
Not having a keyboard attached makes it impossible to enter anything.
Before I uninstall RetroArch and reinstall it, I wanted to see if there was an obvious answer that I am missing? It seems like a start up parameter was dropped during the update, but I have no idea how to reinstate it.
