WiiBuilder is a Windows software to use for Wii homebrew development. This tool can do what wiiload and raw2c are doing, plus all sort of other things. All that in one single executable file. Windows XP or later is required to run the application.


File Section

The File section is use for:

  • Binary file conversion (creating a C array to include into a Wii homebrew project). Allowed file types are:
    • Portable Network Graphics (.png)
    • JPEG images (.jpg or .jpeg)
    • XML (.xml)
    • MPEG-1 Audio Layer 3 (.mp3)
    • MOD (.mod)
    • ScreamTracker 3 (.s3m)
    • Impulse Tracker (.it)
    • FastTracker 2 (.xm)
    • TrueType font (.ttf)
    • ByteMap Font (.bmf)
  • Loading Wii executable files (.dol and .elf) from a computer to a Wii with the Homebrew Channel running. A zip file containing an application could be sent too, it must have one directory in the root of the archive containing the boot.elf/dol file. An IP address must be entered in the Settings
  • Changing the Homebrew Channel themes, just upload the zip file.
  • Building a Makefile, you must have "make" available in your path
  • Converting Images (.gif or .bmp) to header file (.h) for GRRLIB 2.0 or less

You just need to drop a file in the list box. If drag-and-drop is not working (Wine), you could simply right click on the list box to bring the popup menu. From the menu, select Add a File to the List..., in the Open dialog box you could select multiple files. If you don't want to open the software, just drag-and-drop files on the program icon. This is because the software accepts command line, just type WiiBuilder myfile.png. When the files are generated, they overwrite existing ones.

Font Generator Section

The Font Generator section is used to generate a image (PNG or Bitmap) from a specific font on your system. PNG files will have the GRRLIB 3.0 format and Bitmap files will only work with GRRLIB 2.0 or less. Just select the font, size and style you need and click on the Generate Image button to open the Save As dialog box. The antialiasing option only works when you are saving a PNG file.

Homebrew Section

The Homebrew section can be used to view an HBC folder with meta.xml and icon.png.

Color Converter Section

The Color Converter is a tool convert color from one format to another. It could be used to convert colors from 24-bit truecolor to 16-bit highcolor code. Result could be shown in Hex or Dec.

Settings Section

Finally, the Settings section is use to save your configurations in the registry. If you want to delete the software it's best to click on the Clean Registry button to delete all registry entry.
