Next time someone patches the code - please also apply this trivial fix:

Remove the range check in SaveHandler that requires reload and exec addresses to be in the range 00000000-0000FFFF. (Start and end addresses still need to be range checked).

I need to SAVE some code with reload address FFFFxxxx to make sure it's *RUN in the I/O processor. I've patched my own copy, but it's too trivial to be worth me uploading.

Did you amend the disc image writer too? Because as far as I remember, I just set all the extra bits in the catalog to zero (the ones which represent all the high bits of the load/exec addresses and length).

No need. That already wrote bits 16 and 17 from what was passed in.

Oh, did I do it 'properly'? First time for everything...
