In this little introduction, we'll explain what is Grand Theft Auto IV modding and will give you tutorials and support.
Modding consists in modify game's files for a customized version: this will have a graphic change (e.g. textures) or technic change (e.g. handling).
How to create backups
It's one of the most important modding rules: backup files. You need to create a security copy for files that you will mod, to restore in case of problems.
You could create a folder called "Backups" in GTA IV main folder where to put all your original files.
An useful tool is GTA IV Recoverer, that allows you to restore files from game's DVD.
Each modder, newbie or pro, needs his own tools.
To modify text files, e.g. .dat files, you could use Notepad, already installed on your pc.
For 3D modeling and/or conversion, you could use 3D programs such as 3D Studio Max (30 days trial on official site), or Blender. At the moment, importing 3D models is not supported for GTA IV.
All free tools will be uploaded in our download area, in GTA IV Tools section.
SparkIV and OpenIV
