This downloaded content sounds like it could be good place to search for suitable UDE/5713 XBE's (those with the XBE_MEDIA_HDD flag

).
What we need is a homebrew utility XBE that'll search the XBOX hard disk drives, walking the directory trees, looking for any XBE's that meet the necessary criteria to be used an an UDE bootstrap, and drop their paths and filenames into a log file on C:\ (for FTPing off

).
That sounds like it could speed up the search. A nice little project, should anyone wish to contribute

.
(I'll have a go at putting something together myself if no one beats me to it and time allows).
