Kheb allows you to see exactly what changes any software makes on your Pocket PC. It works by taking complete snapshots of your PPC’s state, and creating a diff file that shows the changes between snapshots.

Kheb is a useful tool for software developers, ROM chefs, and advanced users.

Changes:

* Improved storage card detection algorithm.
* Improved error reporting – info about the exact problematic registry keyfile is written to error.log file.
* Improved error handling – Kheb recovers from most IO problems (permissions, unconnected network filesystems, etc) and continues running.
* New icon
* “Generate OEM from diff” item is only enabled if there are existing diffs.
* Latest diff is auto selected
* More entries in kheb.ini
