      The name of the BIOS files needed by each emulator are listed in the docs. I don't see the US BIOS file for Picodrive in the listing, do you have the file in the BIOS folder ?

          For Picodrive, yes - but I don't see it in your listing. Do you have that file available in the BIOS folder ?

              Please add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first to your post and the checksum (MD5) of the BIOS files for Picodrive. Make sure the filename is properly capitalized, as specified in the doc page, since Linux is case sensitive.

                    It seems to me you manually installed RetroPie from the retropie user, but you copied some configuration file from another installation, where the installation user was pi and the BIOS folder is set accordingly - with the wrong path. I advise you to not mix-and-match configuration files from different installation types, since they lead to inconsistencies like this.

                        @fattiusmaximus I suggest you start with the RetroPie image directly, there's no point in using the Lite image and to install manually.
