the problem is that changing the media flag in any other xbe's would remove the MS signature from the file... however, I'm not sure if you could, say, put a hacked update.xbe on the disc, and load up crap that way...
Say, how does the hacked update.xbe work on the xbox, anyway? Does it still have the MS sig? I've been somewhat out of the loop, so I haven't a clue how that thing works exactly. If we could patch one of the exploited update.xbe's with the media flag for CDs, it would be the key for a Utopia cd.
Perhaps there's a way to force an update.xbe to look for fonts on the dvd, without screwing up the signature of the file... I'm going to make a new xboxhdm cd, and fool around with possible hacks... or better yet, attempt to get this cd, and rip the files off it, then try to brute-force some fonts into that thing... there's gotta be a way in .... maybe it's something just as simple as the LPC port (not really simple, but MS probably figured that the softmods would be the first hack, then the hard mods... or at least that's how I see it)
