and towards digital distribution on the PlayStation Network in preparation for the launch of the digital-download-only PSP Go, which was the first (and only) PSP model to not include a UMD drive. However the system experienced lackluster sales compared to previous models, with most consumers still choosing the UMD-compatible PSP-3000 model, which continued to be sold alongside the PSP Go. Despite the earlier push for PlayStation Network releases around the PSP Go's launch, over half of the PSP's library was only ever available in UMD format including Crisis Core: Final Fantasy VII and Kingdom Hearts Birth by Sleep, though there have been a few PlayStation Network–only releases since the PSP Go's launch, such as LocoRoco Midnight Carnival. Still, most new games continued to be distributed via UMD, and, aside from those published by SCE, not all have been released on PlayStation Network. In 2011, the PSP-E1000, a budget PSP model with a UMD slot but without Wi-Fi (and thus no internet connectivity), was released, and is the final revision of the PlayStation Portable. Since 2011, there have been no more movies released on UMD. The successor of the PlayStation Portable, the PlayStation Vita, dropped UMD support entirely in a move similar to the PSP Go, focusing instead on digital downloads and opting for low-profile flash-based media for its retail software. The year 2014 marked the discontinuation of the PlayStation Portable, which rendered UMDs no longer available. Third-party tooling UMD can be dumped into normal disc image files (.iso or .cso), using a cracked PSP for the optical drive. This file can be loaded by a cracked PSP or PS Vita from a MemoryStick, using a hacked version of the game download functionality.
