[THIS WAS NOT MADE BY ME, I AM SIMPLY UPLOADING THIS FOR OTHERS TO USE, THE ORIGINAL SITE: http://openiv.com/ ]

This program allows users to modify GTAIV's archives in order to implement additional files [such as mods] for in-game use.

If the game crashes upon loading a game save, use xliveless ( http://gtaforums.com/topic/388658-relgtaiv-xliveless/ ) AND/OR grab a stock version of all the files modded that caused the crash.
