I d/l'd Project Firestart. BizHawk can see it and get it started. I get to the point where you see the blue EA screen as in this video at this
timestamp. In the video, it soon turns black but for me it never does. Instead these blue disconnected bars keep running down the sides ad infinitum. I believe that means it can't see the right disk. Trouble is I have no idea how to aid this. The "C64" tab has "disks" grayed out. So are the ROMs and disks not the same thing? It says something about disks 1 through 4 in one of the screens shown before, and also disk sides 1 and 2.
See
this for some screenshots. There's some info about the disks that I don't really understand. What do I need to do to get it to a state where it plays well, preferably without having to swap disks at all if possible?
I have in the Sync Settings selected 1541II for the disk drive type but I first tried 1541.
