## Intro
|
|
|
|
In this repository you'll find the fully reversed source code for GTA III ([master](tree/master) branch) and GTA VC ([miami](tree/miami) branch).
|
|
|
|
It has been tested and works on Windows, Linux and FreeBSD, on x86, amd64, arm and arm64.\
|
|
Rendering is handled either by original RenderWare (D3D8)
|
|
or the reimplementation [librw](https://github.com/aap/librw) (D3D9, OpenGL 2.1 or above, OpenGL ES 2.0 or above).\
|
|
Audio is done with MSS (using dlls from original GTA) or OpenAL.
|
|
|
|
We cannot build for PS2 or Xbox yet. If you're interested in doing so, get in touch with us.
|
|
|
|
## How can I try it?
|
|
|
|
- reVC requires game assets to work, so you **must** own [a copy of GTA Vice City](https://store.steampowered.com/app/12110/Grand_Theft_Auto_Vice_City/).
|
|
- Build reVC or download the latest nightly build:
|
|
- [Windows D3D9 MSS 32bit](https://nightly.link/GTAmodding/re3/workflows/reVC_msvc_x86/miami/reVC_Release_win-x86-librw_d3d9-mss.zip)
|
|
- [Windows D3D9 64bit](https://nightly.link/GTAmodding/re3/workflows/reVC_msvc_amd64/miami/reVC_Release_win-amd64-librw_d3d9-oal.zip)
|
|
- [Windows OpenGL 64bit](https://nightly.link/GTAmodding/re3/workflows/reVC_msvc_amd64/miami/reVC_Release_win-amd64-librw_gl3_glfw-oal.zip)
|
|
- [Linux 64bit](https://nightly.link/GTAmodding/re3/workflows/build-cmake-conan/miami/ubuntu-latest-gl3.zip)
|
|
- [MacOS 64bit](https://nightly.link/GTAmodding/re3/workflows/build-cmake-conan/miami/macos-latest-gl3.zip)
|
|
- Copy the files from the `gamefiles` directory to your game root directory. (This is not strictly necessary but very much recommended)
|
|
- Move reVC executable to GTA VC directory and run it.

## Improvements
|
|
|
|
We have implemented a number of changes and improvements to the original game.
|
|
They can be configured in `core/config.h`.
|
|
Some of them can be toggled at runtime, some cannot.
|
|
|
|
* Fixed a lot of smaller and bigger bugs
|
|
* User files (saves and settings) stored in GTA root directory
|
|
* Settings stored in reVC.ini file instead of gta_vc.set
|
|
* Debug menu to do and change various things (Ctrl-M to open)
|
|
* Debug camera (Ctrl-B to toggle)
|
|
* Rotatable camera
|
|
* Xinput controller support (Windows)
|
|
* No loading screens between islands ("map memory usage" in menu)
|
|
* Rendering
|
|
* Widescreen support (properly scaled HUD, Menu and FOV)
|
|
* PS2 MatFX (vehicle reflections)
|
|
* PS2 alpha test (better rendering of transparency)
|
|
* Xbox vehicle rendering
|
|
* Xbox world lightmap rendering (needs Xbox map)
|
|
* Xbox ped rim light
|
|
* Xbox screen rain droplets
|
|
* More customizable colourfilter
|
|
* Menu
|
|
* More options
|
|
* Controller configuration menu
|
|
* ...
|
|
* Can load DFFs and TXDs from other platforms, possibly with a performance penalty
|
|
* ...
|
|
|
|
## To-Do
|
|
|
|
The following things would be nice to have/do:
|
|
|
|
* Fix physics for high FPS
|
|
* [PS2 port](https://github.com/GTAmodding/re3/wiki/PS2-port)
|
|
* Xbox port (not quite as important)
|
|
* reverse remaining unused/debug functions
|
|
* compare Codewarrior build with original binary for more accurate code (very tedious)
|
|
|
|
## Modding
|
|
|
|
Asset modifications (models, texture, handling, script, ...) should work the same way as with original GTA for the most part.
|
|
|
|
Mods that make changes to the code (dll/asi, CLEO, limit adjusters) will *not* work.
|
|
Some things these mods do are already implemented in re3 (much of SkyGFX, GInput, SilentPatch, Widescreen fix),
|
|
others can easily be achieved (increasing limis, see `config.h`),
|
|
others will simply have to be rewritten and integrated into the code directly.
|
|
Sorry for the inconvenience.
|
|

|
## Building from Source
|
|
|
|
When using premake, you may want to point GTA_VC_RE_DIR environment variable to GTA Vice City root folder, if you want executable to be moved there via post-build script.
|
|
|
|
<details><summary>Linux Premake</summary>
|
|
|
|
For Linux using premake, proceed: [Building on Linux](https://github.com/GTAmodding/re3/wiki/Building-on-Linux)
|
|
|
|
</details>
|
|
|
|
<details><summary>Linux Conan</summary>
|
|
|
|
Obtain source code.
|
|
```
|
|
git clone https://github.com/GTAmodding/re3.git reVC -b miami
|
|
cd reVC
|
|
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 .. reVC/master@ -if build -o reVC:audio=openal -o librw:platform=gl3 -o librw:gl3_gfxlib=glfw --build missing -s reVC:build_type=RelWithDebInfo -s librw:build_type=RelWithDebInfo
|
|
conan build .. -if build -bf build -pf package
|
|
```
|
|
</details>
|
|
|
|
<details><summary>FreeBSD</summary>
|
|
|
|
For FreeBSD using premake, proceed: [Building on FreeBSD](https://github.com/GTAmodding/re3/wiki/Building-on-FreeBSD)
|
|
|
|
</details>
|
|
|
|
<details><summary>Windows</summary>
|
|
|
|
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](https://github.com/GTAmodding/re3/wiki/Running-OpenAL-build-on-Windows).
|
|
</details>
|
|
|
|
> :information_source: There are various settings in [config.h](https://github.com/GTAmodding/re3/tree/miami/src/core/config.h), you may want to take a look there. i.e. FIX_BUGS define fixes the bugs we've come across.
|
|
|
|
> :information_source: **Did you notice librw?** reVC uses completely homebrew RenderWare-replacement rendering engine; [librw](https://github.com/aap/librw/). librw comes as submodule of reVC, but you also can use LIBRW enviorenment variable to specify path to your own librw.
