CheatersCheetahCheat

Or CCC for short, pronounced KKK. Now in C++!

Building

Linux

1. Install mingw tools. You'll need cmake, g++, and probably headers and some libs.
   On arch i believe they are aur/mingw-w64-cmake and mingw-w64 package group
2. ./build-static or ./build but then you'll need to copy these libraries to game root: libgcc_s_seh-1.dll libssp-0.dll libstdc++-6.dll libwinpthread-1.dll
3. cp ./build/winhttp.dll ~/.steam/steam/steamapps/common/Cheaters Cheetah/ (or set -DCMAKE_RUNTIME_OUTPUT_DIRECTORY=...)
4. WINEDLLOVERRIDES="winhttp.dll=n,b" %command% into the game's launch options

It also works alongside bepinex/doorstop if you rename it to winhttp_alt.dll (or set -DCCC_PROXY_LIB_NAME="winhttp_alt")

Windows

Dunno man i think you just download cmake and a build system like make, nmake, or ninja and then you do cmake . and cmake --build .

Debugging

./gdb or PROTON_WAIT_ATTACH=1 launch option and ./gdbwait if you need a very early attach (sometimes doesn't work on first time)

You may need to skip sigsegv for a bit after launching if you're using bepinex. handle SIGSEGV nostop noprint pass handle SIGSEGV stop pass

Why the C++ rewrite?

There is a bug in HarmonyX that is borderline impossible to debug behind 50 layers of abstractions plus shitty gdb wine support situation.

It's all a wrapper around il2cpp api calls and other native stuff anyway with its own CoreCLR runtime separate from unity.

And there are like 33 players peak in the game so like who even gives a shit this is all a "haha cheat for a cheat game" shitpost and an exercise in wine/unity hacking

Notes

If you're using clion, switch to ReShaper C++
and create MinGW toolchain with Settings -> Build, Execution, Deployment -> Toolchains -> add
and Cmake -> profile -> toolchain -> select MinGW option

Original C# code can be found in csharp branch

This gist was very useful

Il2CppDumper Honestly should be used instead of manual work, but the generated files are just so massive, and it would require a lot of code generation code in python or something, so i didn't bother.

Credits to:

• UnityDoorstop, bepinex for some api and proxy reference and etc
• Probably some lads on unknowncheats for something
• ByNameModding is an interesting reference
• Il2CppInspectorPro for headers (not a submodule because holy shit 1.4 GiB of unit tests)

Launching a second game instance as a spacewar appid

1. firejail --name=steam --private=/mnt/hdd/steamfirejail --private-dev --private-tmp --net=enp4s0 steam (replace enp4s0 with your own network interface and /mnt/hdd/steamfirejail with your desired home sandbox folder)
2. Install and launch the game from an account that owns it
3. Switch to another account (doesn't need to own the game)
4. cp ./launchgame /mnt/hdd/steamfirejail
5. echo -n 480 > "/mnt/hdd/steamfirejail/.local/share/Steam/steamapps/common/Cheaters Cheetah/steam_appid.txt"
6. Install CCC into the sandboxed game instance otherwise it'll exit on start with appid mismatch error.
7. firejail --join=steam bash ./launchgame -c

Launching primary game instance as a spacewar appid can be done by putting 480 into steam_appid.txt in the game folder, and ./launchgame -c

This can be useful for checking your exploits and cheats from host's POV
