The DMG (Dot Matrix Game) (aka GameBoy) programming tutorial features implementations of various things on the original GameBoy for instruction's sake.
Assembly is written for the RGBDS toolchain (v0.3.3). ROMs are tested in BGB (v 1.5.5) running through Wine on Ubuntu 16.04.
Simply call make from the project root folder to build the ROMs. The ROMs are placed in ./build.
If you don't have make, you can run the following commands (modify as needed):
cd <project_root>
mkdir -p build
rgbasm -i ./ -o build/character_writer.o character_writer/main.asm
rgblink -o build/character_writer.gb build/character_writer.o
rgbfix -v build/character_writer.gb
