Can you check if any of these versions changed the behavior compared to the preceding version? The non-existing command error message wasn't added until 4.0-5531. The older versions may or may not have the same problem regardless of the error message.

/w 4.0-4222 and 4.0-1592 no Dolphin error is produced, but the test still fails.

4.0-5531 is the same as 4.0-5823. "DVDInterface tried to execute non-existing command" error from Dolphin and failed test post that.

Taking a consistency perspective on this, it seems other non-existing command errors provide a bit more detail on the command that's not implemented (i.e. "SI:Unknown command (0x43)" error" for controllers).

The behavior you described about the different versions makes sense. I wonder what happens before 4.0-1592, though. It probably still fails like 4.0-1592, but I can't be sure.

The "non-existing command" error is actually a bit confusingly written. It doesn't mean that there is a command but that the command type is not recognized - it means that DVDInterface is supposed to be executing a command right now, but that its command "slot" (for lack of a better word) is empty for some reason. This should only happen if the emulated software starts a new command while one already is executing. No game does this as far as I know, but I do think the service disc does it. It doesn't really make much sense to submit multiple commands like that, and I don't know what Dolphin is supposed to do in this case.

If you're wondering, the standard unknown command error for DVDInterface is "Unknown DVD command %08x - fatal error" as a panic alert and "Unknown command 0x%08x (Buffer 0x%08x, 0x%x)" in the error log, where %08x is the command type.
