The video section is split into various categories.
ROM Hacking contains videos showing different ROM and Savestate hacking techniques along with information on some of the general things you'll need to know to help you learn the skills needed in order to successfully modify the games you are interested in.
Let's Plays contains videos of me playing different ROM hacks and games with a running commentary as I do so. The general aim here is just entertainment but I also go into describing some of the factors I feel contribute to good or bad hacks as I play each game.
Showcase contains videos of fun, interesting or bizarre things I've discovered or created (intentionally or otherwise!) whilst ROM hacking.
