Yo, if anyone can help, how do I get working, I put the "H" bin in the root as directed, and put the slim.tiff in the picture section, fireware is 5.03 (just updated to see) and it keeps freezing, I reset the psp itself, I turned UMD auto read off, and theme is standard, no go...I tried putting in the whole slim folder, I put just the slim tiff with the other pictures in the folder and all it does is freeze...any clue?
(if this works then I won't need to hack it mostly now :) )
