Please, test this unlock edat files for the "Tennis In The Face" in the attached archive...
There's also attached my custom make_npdata.exe to sign C00, here I did it exactly the same way as make_c00_edat.exe

To decrypt using this command:

make_npdata -d real_file_name dec_file 1

To encrypt using this command:

make_npdata -e dec_file real_file_name 1 1 1 0 16 3 01 Content_ID 1

real_file_name = when encryption is necessarily required to use the original name from Content_ID white extension, because acting as a hash encryption/decryption key in position 0x50 (NPD hash 1 (CID-FN hash - real file name with extension))
