In Valve games, the Game Coordinator (GC) is a backend service most notably responsible for matchmaking and inventory management (like loadouts and skins). This project redirects the GC traffic to a custom, in-process implementation.

While it's still possible to connect CS:GO to CS2's GC by spoofing the version number, this may break in the future if Valve updates the GC protocol. This project aims to restore most GC-related functionality without relying on a centralized server.

• Editable inventory (inventory.txt)
• Item equipping
• Opening cases (including sticker capsules, patch packs, graffiti boxes and music kit boxes)
• Graffiti support
• Weapon StatTrak support
• Stickers and patches
• Name tags
• Music kits
• In-game store
• Works without full Steam API emulation
• Full Windows, Linux and macOS support
• Functional lobbies
• Dedicated server support
• Functional server browser (only shows csgo_gc servers by default)
• Networking using Steam's P2P interface

• Rest of the core features (trade ups, souvenirs, storage units, StatTrak swaps...)

I'm still looking for the full CS:GO Item Schema. If you have a relatively recent copy of it and are willing to share it, let me know!

• Matchmaking (can't be implemented without a centralized server)

• Download CS:GO from Steam
• Download the latest release for your platform from the releases page
• Navigate to the game's installation directory
• Back up your existing launcher executables as they'll be overwritten (i.e. csgo.exe, srcds.exe, csgo_linux64, etc.)
• Extract the contents of the downloaded archive to your game directory, replace the executables when prompted
• Launch the game. If you get the annoying VAC message box, launch the game with the -steam argument
• macOS users: The release binaries are not notarized, so if you're using them, you'll have to deal with that somehow

For GUI inventory editors, see #82. For manual editing, there is a guide made by someone else here.

See csgo_gc/config.txt for available options.

Requirements:

• Git
• CMake 3.20 or newer
• C++ compiler with C++17 support (VS 2017 or later, Clang 5 or later, GCC 7 or later)

The game is 32-bit on Windows so you need to build as 32-bit:

cmake -A Win32 -B build

Linux dedicated servers are also 32-bit:

cmake -DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32 -DCMAKE_ASM_FLAGS=-m32 -B build

On macOS, you need to build for x86_64 instead of arm64:

cmake -DCMAKE_OSX_ARCHITECTURES=x86_64 -DFUNCHOOK_CPU=x86 -B build

For Linux clients you don't have to specify any additional options.
