If youre really insisting on having the kinda fixed eboot, scroll back in the pages and find it,or go to the website some of the other posters have put up back on page like 96 or something. Suffice it to say though that currently there is no way past where that gets you, any rumors so far about getting further have been proven false.
EDIT: Hmm USBloader may not access the memory stick, the only other reason i can come up with for it being unable to load would be that the game is just not compatible with it, and there are games that still dont work with it so that may be the case.
