#Xlive.dll for gta 4 windows

Note: the save validation вЂњfeatureвЂќ of this version of my wrapper now potentially makes it incompatible with any other game, and previous version of GTA IV. Note: This will not magically fix any form of corruption on your save files if they are corrupted.

Save validation is now disabled, you can load any save.

You do not have to use this tool if you do not want to.

#Xlive.dll for gta 4 windows

A new tool, CopyXLiveResources, is now provided to fix the invisible Games For Windows interface in-game.

Protected buffers have slightly changed to better organize them, they are a single block of data rather than two now (this is only really useful if youвЂ™re writing a trainer for use with my wrapper).Yeah, sorry, IвЂ™m not going to encourage it. Multiplayer functionality of GTA IV is now forcefully disabled, to prevent usage of my wrapper to cheat in multiplayer.By hashing the save and providing the valid CRC32 in the result of a replaced XLiveUnprotectData we can get past this validation, allow us to load other peopleвЂ™s saves as well as letting us modify our saves. I suspect that this process is actually decrypting some memory rather than hashing the save itself, the end result is that a CRC32 hash of a part of the save is extracted, then compared against. ItвЂ™s called twice, with five arguments, none of these arguments point at the save data itself, but at the 360 byte blob at the end of the save file. IвЂ™m not exactly sure how these functions work exactly - other than the fact that the one we are interested in, XLiveUnprotectData, is called in a peculiar way. GTA IV uses these functions to hash and validate its save files. Another feature set provided by the Games For Windows API is various functions for вЂњprotectingвЂќ data (hashing & validating).
