Could someone with FW 2.7 try this eboot out.
(Link deleted; It isn't needed anymore, Siouxsie gave the answer.)
Extract and place in (Drive):/PSP/GAME/UCJS10041 then try and run it from the psp game menu, not through the Eloader.
Tell me of what happens.
Thanks for your co-operation,
P.S No possibility of brickage at all! I just want to know what error you get when trying to run it.
