Have to hand it out to Fabien, he's not just an amazing developer with baffling skills to understand code and graphical routines, his dedication to understanding old games of yore is second to none.
Maybe off-topic, but the rest of the website is a trove of knowledge. As a long-time developer who is now trying to pick up graphics/gaming side of coding ... I'm so glad there are folks generous enough to spend time writing and sharing. Thank you!
