Yes, Episode 3 is available for download. Covering the first half of 1985, we see Nintendo add a handful of new developers for the Famicom, including Jaleco, Konami, and Taito. A few very interesting games are released, but also, in my opinion, the first real duds for the system. Jaleco, in particular, produces a few barely playable titles, and the Taito port of Space Invaders is very disappointing.
On the other hand, we have some historically interesting titles. Will Wright, later of Sim City and The Sims fame, gets his first game, Raid on Bungeling Bay, ported to the Famicom. We also encounter Wrecking Crew, a virtually forgotten Mario Bros game which occupies the uncomfortable position in the franchise between the original Mario Bros and Super Mario Bros. There is also a brief history lesson on video games from the video game craze of the early 80s until the release of the NES in 1985.
