iwmtool

Tool for manipulating mpdata files for CoD4

Quick info:

CoD4 stores multiplayer stats in an encrypted file. This tool is able to encrypt and decrypt the stats file, and is also able to edit stats.

Supported operations:

• convert vanilla iwm0 format to CoD4X ice0 format and vice-versa (basically: encryption and decryption)
• simple stats manipulation

Example:

• Decryption:

$ iwmtool --mode=decrypt --input=mpdata --output=mpdata_decrypted --key=YOUR_CD_KEY

• Encryption:

$ iwmtool --mode=encrypt --input=mpdata --output=mpdata_encrypted --key=YOUR_CD_KEY

• Edit stats: (set total kills to 123)

$ iwmtool --mode=stats --input=mpdata --output=mpdata_edited --index=2303 --set=123

Note: Most stats indices can be found in string tables and game scripts extracted from *_mp.ff files.

Note: You can omit CD-key if you run Windows and CoD4 is properly installed on your PC or if you edit a decrypted mpdata file.
