I'm looking for existing tools to unpack data from Armored Fist 2 with filenames. RES files have filename encryption/compression and share the same format as Comanche 3.

added support

Hey,

These appear to be NovaLogic RESOURCE1 archives and quite some research has been invested into them already. The filenames are XOR'd with repeating bytes: 0xAD, 0xDE, 0xED, and 0xAC.

Attached you will find two files:

• AF2_RES_Unpacker.py | This script will extract .RES files

  • Place AF2_RES_Unpacker.py inside the same directory where the .RES files are and let it rip.

• AF2_LZP1_PNG.py | This script decompresses LZP1 and convert PCX to PNG.

  • Place AF2_LZP1_PNG.py inside the same directory where the .PCX files are and let it rip.

Below you will find the research / projects I briefly mentioned before.

Uh oh I get an error:

Modify the script to fix this error.
