pkgj only has a list of recorded zrifs in it. you get the zrif by purchasing said content. if it's not in there, it may be elsewhere, but games don't automatically work with nonpdrm. they need the zrif to decrypt the downloaded pkg. if no one has bought said content, there's no way to make it work. that's how nonpdrm works. in almost all cases with any system, content has to have been bought to fix as nonpdrm.
