=== Savedata protections ===
Most PSP games have a common encryption system whose encryption key is per-game. The encrypted savedata is often named DATA.BIN. The per-game key can be dumped using a plugin on an actual PSP: SGKeyDumper by qwikrazor87. The savedata can be decrypted on PC using [https://github.com/38-vita-38/psp-save psp-save by 38-vita-38] or [https://github.com/cielavenir/psp-savedata-endecrypter psp-savedata-endecrypter by popsdeco/cielavenir] or [https://github.com/BrianBTB/SED-PC SED-PC by BrianBTB] or on PSP using [https://github.com/bucanero/apollo-psp Apollo Save Tool (PSP) by bucanero] or SED (Savegame Encrypt/Decrypt).
Some PSP games have an additional encryption applied to their savedata. This system was already present in some PlayStation and PlayStation 2 games:
* Tekken 2 and 3 for PS1.
* Bandai Namco Entertainment used a previously unknown feature of PS2 memory cards (per sector encryption on flash raw sectors) to protect the quest data memory card on the System 246 version of Soul Calibur 2 Arcade game. One cannot move the save data from one memory card to another because the game uses the per card crypto seed.
See also [https://github.com/bucanero/save-decrypters/] and [https://community.wemod.com/t/philymasters-security-archive/3923]
Some games store digests in the savedata to ensure integrity.
==== Tekken 6 ====
The first 0x20 bytes of MAINDATA.SAV, GHOST.SAV and REPLAY.SAV of PS3 Tekken 6 are not encrypted and are a sort of header. They contain filesize and maybe digest. The remaining data in the files are encrypted with an unknown algorithm (maybe AES128 with a per-console key based on eid0).
MAINDATA.SAV of PSP Tekken 6 is fully encrypted without any header. The game calls [[Kirk]] command 5 to encrypt/decrypt savedata with a key derived from per-console [[Fuse ID]]. This file can be decrypted on PC with the command <code>psp-save -d KEY.BIN 5 MAINDATA.SAV MAINDATA_DEC.SAV</code> where KEY.BIN is the per-console key. This per-console key can be dumped using Apollo Save Tool (PSP) or derived from the console's [[Fuse ID]].
==== Gladiator Begins Demo ====
==== Gran Turismo ====
==== Invizimals ====
Invizimals PSP game stores a checksum in its savedata. It also maybe encrypts it (to check).

==== SOCOM U.S. Navy SEALs games ====
Custom savedata encryption may concern the following PSP games:
* SOCOM U.S. Navy SEALs: Fireteam Bravo
* SOCOM U.S. Navy SEALs: Fireteam Bravo 2
* SOCOM U.S. Navy SEALs: Fireteam Bravo 3
* SOCOM U.S. Navy SEALs: Tactical Strike
==== Patapon 3 ====
https://github.com/bucanero/save-decrypters/tree/master/patapon3-decrypter
==== Monster Hunter games ====
Monster Hunter PSP and Nintendo 3DS games use a custom encryption system and a custom SHA1 integrity hash. It concerns the following games and DLCs:
* Monster Hunter Freedom Unite (ULUS10391/ULES01213)
* Monster Hunter Portable 2nd G (ULJM05500)
* Monster Hunter Portable 3rd (ULJM05800)
* Quests - MH Freedom Unite (ULUS10391/ULES01213)
* Quests - MH Portable 2nd G (ULJM05500)
* Quests - MH Portable 3rd (ULJM05800)

According to Jeerum (2010), every EA game on PSP gets a buffer overflow if you try hard enough: insert 1 kB or 2 kB into your profile name in the save data.

It is fairly easy to get this exploit to work as it is a buffer overflow in the player's name.
 
The savedata in Gladiator Begins Demo only work on the PSP that created them.
