I found the problem with loading AGD games from the SDDOS version of the archive.
The AGD games have a loader like:I'm getting a FILE? error at line 50.
If I change this to *RUN A1CODE it works.
I think this is what Roland just said, but I didn't make the connection.
The documented behaviour of DOS and SDDOS is:I tripped up on this problem a few of years ago.

The menu program is actually running the selected title from DRIVE 2, for a reason that's no longer important. So I changed the menu to use DRIVE 0, and the AGD titles now work correctly.![=D>]( "Applause")

The documented behaviour of DOS and SDDOS is:
Code:
