+Windows Native
+--------------
+
+Building from Windows is now a thing! It's done using the msys mingw-w64 environment.
+
+
+Install Msys2 https://www.msys2.org/
+- Download and run the installer. After it's installed run Msys2 (Choose the msys2 mingw-w64 64-bit shell)
+- Update the shell tools:
+
+```
+pacman -Syu
+# If needed, close MSYS2, run it again from Start menu. Update the rest with:
+pacman -Su
+```
+
+- Install the tools
+
+```
+pacman -S git mingw-w64-x86_64-gcc
+pacman -S make mingw-w64-x86_64-make
+pacman -S mingw-w64-x86_64-pkg-config # needed for SNES Tracker SDL2 flags
+pacman -S mingw64/mingw-w64-x86_64-cmake # Needed to build wla-dx

+# Optional GDB

+
+
+## Library Dependencies
+
+Compiling natively on Windows actually uses SNES Tracker's cross compilation build system.
+We are compiling these dependencies manually for a few reasons.
+ - To have consistent results as the cross-compile build system expects.
+ - To get certain library support that the official packages don't have (eg. Direct3D on SDL2)
+
+### SDL
+
+```
+wget http://libsdl.org/release/SDL2-2.0.12.tar.gz
+tar -zxf SDL2-2.0.12.tar.gz
+cd SDL2-2.0.12
+./configure --prefix=/c/bazzsys/usr/x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --enable-sdl2-config=no
+make && make install
+```
+
+### Boost
+
+Note: Make sure your msys path is the same as mine below (C:/msys64), or adjust it as necessary.
+```
+wget https://sourceforge.net/projects/boost/files/boost/1.72.0/boost_1_72_0.tar.bz2
+tar -jxf boost_1_72_0.tar.bz2
+cd boost_1_72_0/

+
+# the SNES Tracker build system wants to see libboost_filesystem.dll naming convention like it's used on most other compilation scenarios, but the runtime
+# dependency on the dll will use the crazy name.
