This extends and refactors the original CMake script to make it nicer. The structure of it is loosely based on that used in bs::framework project. - Separate the Main SDK build definitions to its own CMakeLists.txt. Source file lists for each project were also moved to file CMakeSources.cmake, cataloged based on a folder they're in and the filter definitions for VS were added. - During build the executable/library artifacts are now stored in <BUILD_DIR>/<BIN_OR_LIB>/<ARCHITECTURE>/<BUILD_TYPE>. The scripts were modified to reflect that change. - Added most of the build flags from the original VS project with some new one. - Added some properties to explicitly configure the build environment. - Add ability to install the libraries for distribution. - Other small renaming, cleanups and things that I've forgotten.
What's GGPO?
Traditional techniques account for network transmission time by adding delay to a players input, resulting in a sluggish, laggy game-feel. Rollback networking uses input prediction and speculative execution to send player inputs to the game immediately, providing the illusion of a zero-latency network. Using rollback, the same timings, reactions visual and audio queues, and muscle memory your players build up playing offline translate directly online. The GGPO networking SDK is designed to make incorporating rollback networking into new and existing games as easy as possible.

This repository contains the code, documentation, and sample applications for the SDK.
Building
Building GGPO is currently only available on Windows, however efforts are being made to port it to other platforms.
Windows
Windows builds requires both Visual Studio 2019 and CMake. Make sure you've installed both before starting. Make sure to add CMake to your path when installing.
- Run the
build_windows.cmdin the root directory of the SDK to generate the Visual Studio 2019 solution files. - Open
build/GGPO.slnsolution for Visual Studio 2019 to compile.
You can also run the cmake-gui tool if you prefer.
