GRRLIB is a C/C++ 2D Graphics library for Wii application developers. It is essentially a wrapper which presents a friendly interface to the Nintendo GX core. With it, coders can quickly and easily start creating graphical applications.

As of v4.1.0, GRRLIB is supplied as a standard C/C++ library (aka. archive) called ‘libgrrlib’. Because GRRLIB processes JPEG and PNG images, it requires the installation of the ‘libjpeg’ and ‘libpngu’ libraries. ‘libpngu’, in turn, requires ‘libpng’ and ‘libpng’ requires ‘libz’. GRRLIB also has FileIO functions to allow real-time loading and saving of graphical data, and thus also requires ‘libfat’.

Changes:

libpng was updated to version 1.4.4
FreeType updated to version 2.4.3
GRRLIB is compatible with libogc 1.8.4
