Types of PSVita PUP
There are different types of PSVita PUP:
- full -> core system stuff (majority of partitions are found here, most important ones being os0: and vs0:)
- systemdata -> sa0: location
- preinst -> pd0: location
- devkit / testkit: Debug updates for PTEL-XXXX and PDEL-XXXX do not separate into three different PUPs. A single PUP will update all components. Additionally updates for PDEL units contains updates for the CP and probably other development unit specific components.
