1. Making GTA IV moddable:
Unfortunately, at the beginning there is no way to modify GTA IV files, because the game is in "read-only" mode. In order to be able to install mods, you need to install
Xlive Less (supports v126.96.36.199!) (DOWNLOAD)
of Xlive less:
a) unpack the file xlive.dll into the game folder (don't forget to remove the asi loader if there is one)
b) optional: In order to turn on debug logging, unpack the file xlive_d.dll into the game folder and rename it to xlive.dll
c) Start the game

Allmost all objects in-game are using textures. Modifications can be released in two different ways: Some texture mods are released as .wtd and .wdr files, which are file archives GTA IV uses. The other way is to publish mods by releasing the textures itself as PNG files.
In both cases you need a tool which is able to open and edit GTA IV archives. At the moment, there are two programs available:
