Collector unearths long-lost 8-bit Konami games, dumps them for emulation

At this point, you might think the entire history of a major gaming company like Konami would be well and fully documented. But you'd be wrong in the case of Space School, a series of game-like educational Famicom cartridges Konami designed for Japanese elementary school children in the '80s.

Designed in partnership with Japanese broadcaster NHK, the Space School series was never available in stores, and it could only be ordered directly by the schools themselves. The games also made use of a special "QTa" adapter that fitted Konami's specially designed 40-pin cartridges into the 60-pin slot of the Famicom.

Both of those factors made these games some of the rarest and most expensive in the Famicom collector's market. It also made reliable information about the titles hard to find—while a few Space School ROM files were floating around, their unique memory mapper configuration made them practically unplayable on modern emulators.

Enter a collector and YouTuber going by "Russian Geek," who managed to track down both a Space School cartridge (Part 1 of the "5th Grade" set, specifically) and an even rarer QTa adapter by scouring multiple Japanese auction sites (and spending hundreds of Patreon-provided dollars). In a lengthy video (Russian with English subtitles), Russian Geek lays out how he got access to these rarities and provides the Internet's first real glimpse into how these games look, sound, and play.

The video also features well-known NES hacker CaH4e3 (pronounced "Sanchez"), who took a deep dive into the QTa adapter and cart to decipher its unique memory mapper. While the cart itself just contains simple ROM files, the adapter apparently contains a unique Konami VRC5 microchip that isn't found in any other Nintendo cartridges (though other VRC chips are well-documented). This chip gave the Space School games capabilities similar to an MMC5 game like Castlevania 3, including more on-screen tiles and graphics that appear to "overlay" on top of backgrounds.

    Youtube has combined audio+video streams, audio-only streams, and video-only streams. You can select from among any combination of these with youtube-dl... typically the highest quality audio streams are audio-only and the highest quality video streams are video-only, so presumably the proprietary web player will also select the audio/video stream quality independently. I expect the combined audio+video streams are still used by some older embedded apps in which case your audio quality will indeed be tied to the video quality.
