While Ngaro (Retro's VM) has been well represented on Linux, MacOS, and other Unix-like systems, support for Windows has lagged behind. Thanks to recent work, it is now possible to build a functional Ngaro on Windows. The exact method and tools used are given below. To actually use it you'll also need a copy of font.bmp and forth.image.

Prerequisites:

• Dev C++
• http://prdownloads.sourceforge.net/dev-cpp/devcpp-4.9.9.2_setup.exe
  
• libSDL Runtime
• http://libsdl.org/release/SDL-1.2.13-win32.zip
  
• libSDL Development Libraries (for mingw32)
• http://libsdl.org/release/SDL-devel-1.2.13-mingw32.tar.gz
  
• Retro Development Kit (rdev)
• Get the latest one from http://retroforth.org
  

Process:

1. Install Dev C++
2. Unzip the SDL runtime and copy SDL.dll to C:\WINDOWS
   (This will allow the library to be used system wide)
3. Unzip the SDL development libraries and copy the contents of i386-mingw32msvc\include\SDL to C:\Dev-C++\Include
4. Copy the libraries from the i386-mingw32msvc\lib to C:\Dev-C++\Lib
5. Create a new empty Dev C++ project and add the following files from rdev\ngaro to it:
1. endian.c
2. functions.h
3. loader.c
4. ngaro_windows.c
5. sdl_devices.c
6. vm.c
7. vm.h
6. Go to Project -> Options and add the following to the Compiler commands text box:
   -DUSE_SDL
7. Go to Project -> Options and add the following to the Linker commands:
   -lmingw32 -lSDLmain -lSDL -mwindows
8. Compile everything
