Attempt at reverse engineering and improving GTA IV

Reverse Engineering and improving GTA 4 :) IV Definitive Edition

About

This project attempts to be a fixed version of iv-sdk for GTA 4 : Complete Edition. Currently compiles as a dll that can be injected at game start. For now it's still a W.I.P, if you inject it it will open a console with the addresses it managed to grab

CE-Only support for now. non CE will come very soon

Features

• Grabbing 9 addresses ??? that's it lmao, reverse engineering is a tough activity and you barely get instant gratification

• Improved eyestep , i added some useful features that ill share some day as a standalone

IDEAS

• maybe add a lua environnement ? with ability to hook functions on the fly too (like Il2CppLua)

Building

Get xmake from XMake's github page.

git clone --recursive https://github.com/elcapor/gta4-modern.git
cd gta4-modern
xmake

Structure

gta4 -> all the dll code

Note

im tired of writing sick readmes for stuff i dont finish 💀

BTW the dll unloads itself when u tell it to (this is broken for now iirc)

I found all the patterns by myself, i didn't take a single pattern from anyone's code, anyone who claims the opposite is deliberately lying and propagating misinformation.

TODO

[] - Make asserts and more checking for AOBs W.I.P

[] - write a get near func - W.I.P

[] - uml diagram - lazy to do this ong
