okay folks i see alot of people are having troubles getting resistance 3 to work i found the fastest and simplest solution to get it to work, first off with disk in drive it says unsupported data but do not worry go into app home and press start after using mulitman in app home press start when resistance 3 screen and sound appears.
i just installed update 1.02 only and then geohot 3.55 fix here are the links they are not my links but thought i wold make it easier for all this way first make sure all old resistance 3 game data is deleted.
1) install (Game Update 1.02) http://b0.ww.np.dl.playstation.net/t...2-V0100-PE.pkg
then go into multiman press start on resistance 3 then when in xmb the disk will say unsupported data go into app home and press start on resistance 3 through their, also i got it to work on external and it was the duplex release BCES-01118-[Resistance 3] and that is all this should get everyone running this wicked game amazing totally it only works with eur version and not usa version.
also you have to get the eboot and param sfo before starting resistance 3 and overwrite them with originals here are links again not mine were on this site.
param.sfo file = https://rapidshare.com/files/3267445821/PARAM.SFO
eboot file = 2 links http://rghost.net/39513400
then you got yourself a fantastic game folks enjoy, it is straight forward and like i said i installed on external not internal hard drive and it was the BCES-01118 = duplex version works like a charm.
