We're using a (very slightly) modified WMA Pro decoder to handle XMA packets. The diff used is included.
- Install MSYS2 x64
- pacman -Sy
- pacman -S patch yasm
- mv /usr/bin/link /usr/bin/link-bak
- Launch msys shell
- "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat"
- 'which links.exe' must return the x64 linker
