ME version works fine for me...are you putting it in the game150 folder? or if you set it the opposite, in the game folder?
did you try combining it to a 1.0 eboot?
unfortunatly, when you have folder and folder%, folder will show up corrupt wether you are hiding corrupt icons or not.
my solution? i used psp brew to turn all my 1.50 folder and folder%'s into 1.00 folder's and problem solved.
any other corrupt icons means they need to be "fixed"....check dark_alex's readme for info on that, where he mentions irshell problems...
http://pspupdates.qj.net/index.php?pg=49&aid=69593 <--- one of many programs that "fix" these corrupt homebrew....the problem is in the param.sfo, so if you unpack a working eboot, take the param.sfo, unpack the corrupt eboot, replace the sfo with the working sfo, repack it, it will work! you'll just need to change the homebrew's name w/ some kind of homebrew customizer.
