PSP DOCUMENT.DAT Decrypter/Unpacker

Scripts for decrypting and unpacking png from PS1 on PSP/ePSP/PS3, PSP and Minis manuals.

Both scripts support manuals with more than 100 pages.

To use the scripts, Python 3.12+ is required, and the pycryptodome package must be installed.

decrypt_document_ps1.py

• For PS1 on PSP/ePSP/PS3manuals.

Copy DOCUMENT.DAT files into the in_ps1docs folder using any filename with the .DAT extension.

The script will create an out_png_ps1 folder containing all pages.

Additionally, the decrypted DOCUMENT_DEC.DAT (only for PSP CFW) file will be saved in the out_dat_ps1 folder.

decrypt_document_psp.py

• For PSP Game and Minis manuals.

Copy DOCUMENT.DAT and DOCINFO.EDAT (if present) into the in_pspdocs folder, adding a prefix to the filenames (for example: GAME_ULUS12345_DOCUMENT.DAT and GAME_ULUS12345_DOCINFO.EDAT, respectively).

The script will create an out_png_psp folder containing all pages.

Additionally, a re-encrypted DOCUMENT.DAT using the default key (to get rid of the DOCINFO.EDAT file requirement) will be saved in the out_dat_psp folder.

DOCUMENT.DAT format
