Furthermore, a critical limitation persisted: . A digital-only game (e.g., Journey or Tokyo Jungle ), which was never pressed onto a Blu-ray disc, lacks the required disc metadata—such as the PS3_DISC.SFB file and specific region codes. Attempting to force such a PKG into an ISO structure would result in a non-functional image that fails to boot on any firmware. Conversely, a physical disc release that also had a digital version (e.g., The Last of Us ) could be successfully reconstructed.
