I have Untold Legends, it was the first game a got. the whole reason i bought a PSP intially was because of that game (i friend loaned me his PSP for a day). Then i beat it in 3 days, made 2 more chars, and maxed them to lvl 50 in 2 weeks. I like d2 better. the graphics in untold aren't bad, but there are aspects of d2 i like better, set items, uniques, a larger char selection, more unique skill selection. more Replay value is the bigger issue; i haven't even touched untold legends in 2 months; i play d2 almost daily.

this is my train of thought....
Come up with a eboot for D2
use a modified installation from the cds
use a modified iso of the "play" disc (i realize that this may limit use to FW 1.5 for now)
there may be other ways.. i am still researching. i am very new to the scene, but like what others have done and i want to contribute as well.
