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

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.
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.
For now, though, the world can enjoy some new "classic" Konami chiptunes and long-lost pixel art from the golden age of 8-bit gaming.
