Among the material uncovered in the 2020 Gigaleak, a large-scale breach of internal server data from Nintendo, are a pair of emails describing a proposed "21st Century Version of Famicom" as a "fourth pillar" for the Wii Virtual Console alongside NES, SNES, and N64 emulation. According to these correspondences, the idea was the brainchild of Wii lead developer Genyo Takeda and would've consisted of emulated NES games with improved graphics. The concept progressed towards an early testing phase, but was ultimately scrapped to focus more on developing the Virtual Console's SNES emulator.
