We've recently come across a rather extensive listing of home-grown Windows CE tools, most of them apparently targeted at Windows Mobile devices but also of use on customized CE devices as well.  The very bare-bones site (who needs graphics when you're only browsing utilities?) bills itself as offering "a collection of tools to do many things to a windows CE device via ActiveSync/RAPI."  Some tools are noted as being based on the sample code included in the PocketPC SDK, and most are available in both source and binary form.

One thing to take into account is the site's warning that "experimental tools may not work, or may even cause damage."  Use them at your own risk -- which is good advice whenever you're utilizing a utility created by someone other than yourself.

You'll find this community resource at: http://www.xs4all.nl/~itsme/projects/xda/tools.html.
