This tool adds a more detailed Discord-RPC to the game. It's a seperate program, so it works on servers without client modification.
For the 64 and 32 bit versions of the game, you need diffrent versions of this tool. Using x64 version of this tool and x32 version fo the game, this will NOT work. By default the 32 bit version of the game is installed. You can change this by enabling the chromium beta in steam.
This tool works by reading the games memory. It reads the bytes at a certain address that are diffrent for the 2 versions of the game.
