Replying to myself.

The issue with Terrapin is different: it needs a relatively standard DOS (ProntoDOS seems to work so long as the free space patch is diabled, same prolly holds true for the mutated version I use on most of my disks), and it needs MAXFILES to be 1 (or CATALOG will destroy it). I haven't yet successfully figured out a way to do it, which I am thinking would need to be "unhook DOS, adjust MAXFILES by hand, reconnect DOS and then run the program".

Didn't have to.

I set a breakpoint for the entry address ($1BF6), then dumped memory. Wrote a mover to shuttle down the bottom 1K, then attached the image from $1BF6 up to $BFFF. It works like a charm. Even when booted from RDOS.

Pity I couldn't Exomize Apple Logo, though.  Still, Terrapin's not bad.
I have now added Terrapin Logo to my list of programs destined for "Educrunch".

-uso.
