Knowledge base index
SEGA history runs from arcade machines and home consoles to handhelds, unusual add-ons, blue-spined game cases and series that remained recognisable long after the company stopped producing its own consoles.
This index brings together GamingPlanet dossiers and articles about SEGA hardware, games, collecting and preservation. It is intended to grow from a broad starting point into separate pages about individual systems, regional differences and important releases.
Use this page as the starting point for SEGA console history, arcade technology, games, physical releases and the practical problems involved in keeping that material usable.
SEGA did not move through one simple line of machines. The Master System, Mega Drive, Saturn and Dreamcast each came from a different technical moment, while regional names and release schedules made the family tree even less tidy.
Future dossiers can give every system its own factsheet, model overview, media formats, accessories and recommended starting points. Until then, the SEGA article archive collects the existing coverage.
SEGA console history is difficult to separate from arcade hardware. Controllers, chips, conversions and even unsuccessful technical routes often explain why a home release looks or behaves the way it does.
The hardware archive is the current route to stories about boards, graphics technology and the unexpected links between SEGA and PC gaming.
Sonic may be the best-known SEGA character, but the wider catalogue also covers arcade racing, fighting games, RPGs, strategy, experimental peripherals and series that later continued on other platforms.
Open the Sonic archive or browse all SEGA articles.
A SEGA collection can contain cartridges, jewel cases, large plastic cases, cardboard sleeves, GD-ROMs, registration cards and hardware that differs by region. The same game may have another title, cover or even another console name elsewhere.
Use the condition report when recording completeness and condition.
Preserving a SEGA game can also require controller support, save batteries, optical-drive knowledge, network context, manuals and information about the hardware for which it was designed.
The first logical dossiers are the Master System, Mega Drive or Genesis, Saturn and Dreamcast. Separate pages can then cover Game Gear, Mega-CD, 32X, arcade systems, regional collecting and individual game series.
