Intro

The aim of this project is to reverse GTA III for PC by replacing parts of the game one by one such that we have a working game at all times.

How can I try it?

  • re3 requires game assets to work, so you must own a copy of GTA III.
  • Build re3 or download the latest nightly build (You must be logged in.)
  • (Optional) If you want to use optional features like Russian language or menu map, copy the files in /gamefiles folder to your game root folder.
  • Move re3 executable to GTA 3 directory and run it.

Latest standalone executables to download

(Put content of selected archive into gamedir)

Building from Source

When using premake, you may want to point GTA_III_RE_DIR environment variable to GTA3 root folder, if you want executable to be moved there via post-build script.

Linux Premake

For Linux using premake, proceed: Building on Linux

Linux Conan

Obtain source code.

git clone https://github.com/GTAmodding/re3.git
cd re3
git submodule init
git submodule update --recursive

Install python and conan, and then run build.

conan export vendor/librw librw/master@
mkdir build
cd build
conan install .. re3/master@ -if build -o re3:audio=openal -o librw:platform=gl3 -o librw:gl3_gfxlib=glfw --build missing -s re3:build_type=RelWithDebInfo -s librw:build_type=RelWithDebInfo
conan build .. -if build -bf build -pf package
FreeBSD

For FreeBSD using premake, proceed: Building on FreeBSD

Windows

Assuming you have Visual Studio:

  • Clone the repo using the argument --recursive.
  • Run one of the premake-vsXXXX.cmd variants on root folder.
  • Open the project via Visual Studio

If you use 64-bit D3D9: We don't ship 64-bit Dx9 SDK. You need to download it from Microsoft if you don't have it(although it should come pre-installed after some Windows version)

If you choose OpenAL on Windows You must read Running OpenAL build on Windows.

There are various settings in config.h, you may want to take a look there. i.e. FIX_BUGS define fixes the bugs we've come across.

Did you notice librw? re3 uses completely homebrew RenderWare-replacement rendering engine; librw. librw comes as submodule of re3, but you also can use LIBRW enviorenment variable to specify path to your own librw.
