re3

Build Status

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 it from one of the above links (Debug or Release).
  • (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.exe to GTA 3 directory and run it.

Preparing the environment for building

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.

  • For Linux, proceed: Building on Linux
  • For FreeBSD, proceed: Building on FreeBSD
  • For 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)

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

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

ℹ️ 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.
