Double Dash Deluxe is a work-in-progress open-source (AGPLv3), cross-platform (GameCube, Wii, vWii, Dolphin Emulator) mod for MKDD aiming to provide a variety of features and improvements over the base game, including online gameplay.

This is in an early state and not yet useful for regular players. As such, binary releases are currently not provided.

You need:

• Python 3.11 or later
• Ninja
• cargo
• LLVM 22

The used compiler is NXP 'CodeWarrior Special Edition' for MPC55xx/MPC56xx v2.10. You can run tools/prepare.sh which will extract the relevant files from the installer with 7-Zip, or do the same manually. To use the compiler on non-Windows platforms, a Wine installation is needed.

If you already have the compiler installed, you can find the relevant files in C:\Program Files (x86)\Freescale\CW for MPC55xx and MPC56xx 2.10 and manually move them.

• ./license.dat -> tools/cw/license.dat
• ./bin/lmgr11.dll -> tools/cw/lmgr11.dll
• ./PowerPC_EABI_Tools/Command_Line_Tools/mwcceppc.exe -> tools/cw/mwcceppc.exe

You can then simply run build.py to build the project. The build/ddd directory will contain the generated binary.

You can launch build/tests to run all tests.

format.py # C++
cargo fmt # Rust
