I think the region free TU should work on pal version try it here is the link http://www.xbuc.net/browse/dynasty-warriors-8/
How are you trying to install the TU? also whats the game title id of pal version if its 4B5607E5 then the the TU should work
yeah thats what i dont understand, that is the folder number, i put the title update in the cache folder and in the 4B5607E5/000B0000/title update. not sure what else to do. but thanks for the help +rep
Ok if you have freestyle dash installed go to games and click on the game then y for options then title updates and see if the tu is set it should be gray if its not set and green if its set also an easier way is to use horizon to inject the tu through package manager into a usb and then move it to HDD that should work im sure of it.
