I wondered why the calculation for a room's main loop patch vector
had the base address #C0FD in your reply here but was given as
#C0FB in the advanced trainer. I noticed that both these will work
because the default 9F 86 normally appears twice in the resulting
room data.

Offset #FD is for the main-loop patch-vector, which is called every time-frame. The default is #869F.

Offset #FB is for the room-setup patch-vector, which is called when you enter the room. The default is #869F.

Offset #F9 is for the portal patch-vector, which is called when you enter the portal (in rooms that have one). The default is #86A0, which behaves like the original Manic Miner.
