More details: When extracting the files from either the PS3 or Xbox 360 version of the game, under the /resource/gscript/ folder, there are .scb files that contain the dialogue for the game.

~~These seem to be either encrypted text or encrypted archives that contain the text for the game.~~ These .scb files are some sort of scripts that load the dialogue for the game, with scenes, text and more. They are encrypted in AES 192. The .dec files included in the link are the decrypted script files used for the game. These are encoded in UTF 16 Big Endian.... sort of. The dialogue in the game is UTF 16 BE for certain, but the pointers/references to other script files are almost definitely encoded in UTF 8. The imas2dec.zip file contains the decryption executable used for the games' files.

Sample files (if possible):

(Contains 7 files for reference)

DELETE ME: Do not attach files to the issue directly. Please use links to files hosted on other sites like Google Drive, Mega or similar.
