Minecraft Dungeons II on Linux

A local stand-in for Microsoft Gaming Services so Minecraft Dungeons II (Steam app 1912410) can start under Proton. The game looks for xgameruntime.dll. This repository builds that DLL. It does not modify the game and it does not include Microsoft's library.

Install

Start the game once from Steam and close it, so Proton creates its prefix. Then run:

curl -fsSL https://raw.githubusercontent.com/mahirsn/Dungeons2_linux_fix/main/install.sh | sh

Run the same command again to update. If Steam is not in ~/.local/share/Steam, set STEAM_ROOT.

First sign-in

Start the game from Steam. A window shows a code and opens https://www.microsoft.com/link. Enter the code and sign in with the Microsoft account that owns your Xbox profile.

The sign-in is cached in ~/.local/share/dungeons2-compat/tokens.txt (mode 0600) and renewed on its own. Do not share that file.

Build

The DLL in src/ is ready to install. To build it yourself:

x86_64-w64-mingw32-gcc-posix -shared -O2 -Wall -Wextra -o src/xgameruntime.dll src/xgameruntime.c
# or
zig cc -target x86_64-windows-gnu -shared -O2 -o src/xgameruntime.dll src/xgameruntime.c
