OpenIV 0.9.2 (250)

A program for viewing, editing and changing GTA 4 resources.
In the new version of July 1, 2011: the ability to fully edit game models (WDR and WDD).

Program features:

• Convenient viewing of GTA IV files through the "Open Content" function;
• Full editing of RPF2 files. You can add, remove or replace any files;
• Viewing and extracting data from RPF3 (file names are shown);
• Full editing of IMG3 files. You can add, remove or replace any files;
• Replacing textures in any *.WTD and *.WHM files. Currently, only PNG format is supported and replacement with files with the same resolution (for example, a 512x512 texture can only be replaced with another 512x512 texture);
• Built-in SCO script decompiler (currently has many bugs);
• Preview for most of the files found in GTA IV;
• You can extract resource files, both in their original compressed form and in unpacked form, for this there is a "Save Contents" function. For example, this function allows you to save all textures from *.WTD file without opening it;
• Using the "View HEX" function, any file can be viewed in HEX mode.

In the new version: rewritten code, which gives greater stability and speed. OpenFormats support included. Compatible with all versions of GTA 4 and EFLC.

Usage:
Open the program, click on the Edit Mod button (Editing mode), proceed to the folder of replaced files, select the replaced files, move them to the window with the program. That's all! You may think that nothing has changed, but you are wrong! The program worked! you just didn't notice it.

If someone gives an error when replacing files, then try moving the downloaded files to the desktop, restart the program and try again.
