knowledge base

SEGA history runs from arcade machines and home consoles to handhelds, unusual add-ons, blue-spined game cases and the Dreamcast as Sega's final in-house console.
Here you will find stories about SEGA systems, hardware, cartridges, cases, regional differences and the place of machines such as the SG-1000 and Dreamcast in game history.
This page brings together the main routes into SEGA hardware, games, collecting and background reading. The SG-1000 page is a good starting point if you want to follow Sega back to its first home console, while the Master System shows where the line became familiar to far more players.
SEGA did not move through one simple line of machines. The SG-1000, Master System, Mega Drive, Saturn and Dreamcast each came from a different technical moment, with different media formats, audiences and regional stories.
SEGA console history is difficult to separate from arcade hardware. Controllers, chips, conversions and even failed technical routes often explain why a home release looks or behaves the way it does.
Sonic may be the best-known SEGA character, but the wider catalogue also covers arcade racing, shooters, RPGs, experimental peripherals and series that later continued on other platforms.
A SEGA collection can include cartridges, jewel cases, larger plastic cases, cardboard sleeves, GD-ROMs, registration cards and hardware that differs by region. The same game may even have another title, cover or console name elsewhere.
Preserving a SEGA game can also require controller support, save batteries, optical-drive knowledge, network context, manuals and information about the original hardware.
These broader routes keep the main page compact while still giving you solid entry points into related topics.
