impacto is an open-source reimplementation of the "MAGES." visual novel engine in C++ and OpenGL. Using the original data files, impacto can run any supported game on any supported platform.
impacto is in active development. At current stage it should be possible to reach all endings in at least one supported game - "Memories Off 6 ~T-Wave~." However, some functionality and architectural design are still missing and no games are fully complete yet. Refer to #1 for supported games and remaining work.
impacto is currently being developed for 64-bit Windows 10 and desktop Linux PCs but we've successfully experimented on macOS, Android (ARM), Switch (homebrew and Linux) and HTML5/WebAssembly (via Emscripten) and full official Android support is planned. OpenGL is used for the graphics renderer with experimental Vulkan and DirectX 9 options available.
For building on Windows with Visual Studio 2019 or newer, please refer to the building instructions.
For building on Linux, see the instructions for Ubuntu 18.04 Desktop and adapt to your distribution if necessary.
More platforms and toolchains are known to work.
We are looking for contributors! Check out the Getting Started guide for pointers on setting up games for testing, finding your way around the codebase and adding functionality. Also check out the Contributor guide for important information on the code style you should follow.
There is work to be done for C++ programmers of any skill level in a wide range of subjects, on game engine architecture (design and implementation), reverse-engineering the original (looking at just the game's outside behaviour as a black box or inspecting the internals through a white box), replicating it, improving on it with new functionality, documenting our efforts, fixing bugs and polish.
If you're interested, come join our Discord to discuss ideas and help you get into it.
impacto source code as a whole is released under the liberal ISC license. Some parts are based on or copied from third-party code under various licenses. Binary distributions or parts thereof may fall under more restrictive licensing terms. See THIRDPARTY.md for details and attribution.
