Key information
A modder named Throaty Mumbo has developed an authentic CD-ROM reader designed specifically for the Nintendo Entertainment System, allowing games to be played from compact discs.
The project, called "NESCD", operates without requiring any modifications to the original NES console itself. Instead, the hardware relies on an extension base resembling the Sega Mega Drive's Mega-CD, upon which the console rests.
The setup utilizes a disc reader, a Raspberry RP2350B, and an Everdrive N8 Pro flash cartridge. When a disc is inserted, the Raspberry reads the game file and transmits it via cable to the cartridge, which tricks the console into reading the digital file as an authentic cartridge.
The custom casing is 3D-printed and features a disc tray, a physical ejection button, and a volume control dial, enabling games like Super Mario Bros. to run directly from a burned CD without a traditional game cartridge.
Throttle Mumbo has published the 3D-printable structure plans, source code, and electronic schematics for free on a dedicated GitHub repository, drawing inspiration from the historical Sony CD-ROM prototype intended for the Super Nintendo.
