Release Info: For those who whish to remain on good old stable CFW 3.55 , DUPLEX brings EBOOT Patches for some of the games recently released. Replace files in your game dir with the ones from our archive. The file model_shader_pack.sdat goes into usrdir/shader/ . Notes: DUPLEX supports valid scene releases only, and no region dupes. DUPLEX will not patch updates for you because we think the base retail version is enough to test out a game.
