mortscript download has files to install both in pda or in desktop pc. The syntax is the same but some commands are restricted to the pda. In addition to xda_uc there are two other threads: the mortscript compendium and mortscript examples. you can restore provxml/xml files with mortscript, xda_uc, sashimi (they are all mortscript), with a cab, with a UC file, runcc, with sk tools and most of backup programs, etc, etc. you can do it sending keys to the screen or writing to the registry / restoring files. You can also restore many things: passwords, voice labels, contacts, configurations, bt pairings, wifi connections, email accounts, weather parameters, etc...It is a whole world but no distributed ROM should contain any registration keys.
