Planet codenames

From Sega Retro

After successfully launching the Sega Saturn, Sega retrospectively gave different codenames from the planets in the Solar System to recently released projects, and used 2 more planets after Saturn for subsequent projects, in order to make sorting documentation out easier in the future.


Codename Equivalent
Mercury Sega Game Gear
Venus Sega Nomad
Earth Unused
Mars Sega 32X
Jupiter Cart-based 32-bit system; abandoned in planning stages in favor of a disc-based system that became known as...
Saturn Final name.
Uranus Unused.[1] Hiroyuki Miyazaki offered a few explanations for this, saying when pronounced in Japanese it sounds like "Uranu" or "won't sell", what he called "an ominous name for a project."
Neptune 32X/Mega Drive combo unit
Pluto Sega Saturn prototype unit featuring a different shell with a NetLink Internet Modem accessory built in. Only two produced. Uses US BIOS.

Furthermore, hardware released around the time the Saturn was had codenames based on Saturn's moons:

Codename Equivalent
Titan Sega Titan Video
Janus Sega Picture Magic

It is unknown whether the Sega CD, Sega Mega Jet, Sega Pico, arcade hardware, or any other Mega Drive/Saturn-related hardware had codenames.

By the time the Sega Dreamcast was planned, Sega had moved on to a new scheme. However during the development of the Mega Drive Mini, due to an urban legend about Earth being the Mega Drive's codename, Hiroyuki Miyazaki decided to give the Mega Drive Mini the codename of "Moon"[2].
