EP9000-CUSA08809_00-SOTC0000000000EU-A0100-V0100.pkg
EP9000 Meaning Europe Region and 9000 is for PSN I think, US/Canada has UP instead of EP, not really sure for different # after EP/UP, maybe for different video games development company such as Square Enix, Santa Monica Studio that released the game via physical version.
CUSA08809_00 is the Title ID
SOTC0000000000EU is the 16 Characters for the Game Title, usually initial of each word in the game title, SOTC for Shadow Of The Colossus, usually filled with 0 after coming up with name for games, such as HORIZONCE0000000 and FARCRY5GAME00000.
A0100 meaning application version 1.00, game dumped without updated merged would be A0100.
V0100 meaning update files version 1.00, so no update. For game that has update combined , it would be something like EP9000-CUSA08809_00-SOTC0000000000EU-A0100-V0106.pkg for update version 1.06
For an update that wasn't merged together with the game, it would have naming convention of EP9000-CUSA08809_00-SOTC0000000000EU-A0106-V0100.pkg 1.06 would be the application version.
