The following isn't intended to be a technical walkthrough, it's just preserving the notes I made when making the patch.


In addition to the notes below, I also took some hand written notes which are scanned in as PNG files in this folder

I was using this to try to locate the ASCII codes for printing the keys on the dungeon main screen but this was a dead end.
