The Family Computer Emulator was one of the first Famicom emulators. The development started in the early 1990s.
It was made by Haruhisa Udagawa(宇田川 治久), a developer at Namco, Sonic Team and KAZe. He also worked on twelve games from the 1980s to the early 2000s.
The emulator was simple, but it was able to run games such as Donkey Kong. The ROM files had to be dumped through a complicated process.
