The code comes from the RGBDS source and documentation zip files found
on this website:

The same website reports:
"Best of all, it’s free! That’s right! Free! The executables
are free to use, either for personal hobby use, or full blown
commercial productions — I know of at least a dozen commercial
games you can purchase that are written with RGBDS — and the
source code is free to modify.
"The only thing I ask is that you do not charge for either
distributing the executables or source code, and any derivative
works you give credit to the original authors of the tools.
That means you have to say “Thanks” to the original authors
SurfSmurf and Otaku."
