I saw this today when browsing the bbc website and thought it was a nice interview. Not the sort of thing you tend to see on mainstream media: http://www.bbc.co.uk/news/av/technology-43001916/new-sega-mega-drive-game-made-on-90s-kit Not as indeapth as I'd like but still cool to see.
This guy is interesting, really makes me want to code for the genesis too If you're interested, he did some videos for Computerphile about genesis programming basics (well, not "basics" more of like, adding some numbers together). But still interesting nonetheless
