Structure of files in X-Mem

[grsbanks]

Just wondering if anyone can point me to any hidden resources for this.

I've been doing some work reverse-engineering the data held in the RAM of an HP-41, working off this diagram:

I've nailed the structure of user key assignments and alarm data, I'm just struggling with the organisation of X-Mem right now. If anyone has pointers to information describing the structure, not of the files themselves stored in there because that's obviously application-dependent, but of the data chaining the files together and "telling" the HP-41 what files are there, where they are and what size they are.

Thanks in advance.
