If you're interested in doing so, get in touch with us. - -## Installation - -- 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 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-18.04-gl3.zip) - - [MacOS 64bit x86-64](https://nightly.link/GTAmodding/re3/workflows/build-cmake-conan/miami/macos-latest-gl3.zip) -- Extract the downloaded zip over your GTA VC directory and run reVC. The zip includes the binary, updated and additional gamefiles and in case of OpenAL the required dlls. - -## Screenshots - - - - - - -## 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 -* Improve performance on lower end devices, especially the OpenGL layer on the Raspberry Pi (if you have experience with this, please get in touch) -* [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 the executable to be moved there via post-build script. - -Clone the repository with `git clone --recursive -b miami https://github.com/GTAmodding/re3.git reVC`.
