Game Boy hacking at FOSDEM

A week ago David and I were in Brussels, giving a talk about our first Amsterdam Hackers project at FOSDEM 2019. We explained how we developed a Forth cross-compiler for the original Game Boy by first reverse-engineering a Hello World! binary.

Our talk focusses on the incremental approach we used to hack on a device that we knew nothing about, and shows how well Forth fits into this process:

Although gbforth is far from complete, you can create terminal-based games (like the included Sokoban example) without much hassle already.
