Forked from NMSResign by stk25/emoose on NexusMods.
This tool can recreate the BankSignatures.bin file for you based on your own NMSARC.pak files, which stops the game from showing any "File Tamper Warning" message.
I have updated it with some functionality changes and to fix a bug.
Place the executable in the PCBANKS folder or on PATH. Use the program from the command line or reference it in a script.
-decrypt: Decrypts a .bin file to a .dec file.
-encrypt: Encrypts a .dec file to a .bin file.
-createbin: Creates a new encrypted bin file from the folder of pak files.
-createdec: Creates a new decrypted file bin.dec file from the folder of pak files.
-help: Displays a help message.
All commands now also accept a filename as an additional argument, although this is mostly for testing purposes.
