About JUS, deufeufeu was the author (not only him, but I don't know the details) and there is no homepage anymore.
Download links:
http://filetrip.net/f5727-Jump-Ultimate-Stars-English-Translation-Patch--May-3-2008.html (probably the same as the "full" one)
http://kkddl.free.fr/jus/file/jus-eng-dev03_05_08.zip (full)
http://kkddl.free.fr/jus/file/jus-eng-dev03_05_08_nokoma.zip (no koma)

The only difference between the 2 versions seems to be that one has the koma graphics translated and, the other, doesn't (in case you prefer the original look).

EDIT
Nice topic.
