What is this? - An injection and extraction tool for the texture format .XTD of the Xbox 360 version of GTA IV, the first ever released .
How to use? - Just extract any .XTD file from your ISO via OpenIV, open it up in the xtd section of the program. Extract one or all of the .dds files that are in your .XTD. Open the .dds files via Photoshop or any photo editing tool. After finished inject it back, you can swap PC .dds textures for the 360 ones. In the viewer, pay attention to the DXT format and levels as you will have to save it like that in photoshop for it to work. Thanks to Pimpin Tyler and Anthony for completing and finally releasing the build and source.
