Reverse engineer Amiga monitor files

Question

The files found in Devs:Monitors in AmigaOS, what do they contain?

What is their internal format? How do you go about patching one or creating one from scratch?

Answer 1

The Amiga program MonEd (http://aminet.net/package/driver/moni/MonEd3a) is an editor for these files. It comes with source, which may well indicate something about the structure.

It also notes:

Then click on save to store this information in the TOOL TYPES of monitor which is stored in DEVS:Monitors/

which may have something to do with the file size.
