Commands

# Command
acts dp <pool>

# Example
acts dp stringtable

Some dumpers are writing to Compiled Files (.cf), the command cfd (cf dump) can extract them.

# Command
acts cfd <files>

# Example
acts cfd output_dump

GSC Decrypter

For the games after cw, the function to decrypt the strings isn't integrated inside acts. The scripts should be decrypted before giving them to the decompiler.

This method requires a dumped exe of the game and will execute it.

# Decrypt the scripts
acts scripts_decrypt <dumped game executable> <game> <encrypted dump> <output dir>

# Example with a cw dump
acts scripts_decrypt BlackOpsColdWar_dump.exe cw gsc_dump gsc_dump_dec

ACTS Lib

Prototype libary for random stuff, probably not linked to Call of Duty.

Lookup

To have a lookup over the extracted hashes, you can use a file named strings.txt when using the process, it will be loaded automatically, one string per line.

You can also use .wni compiled files, create a directory with the name package_index and put the .wni files in it.
