The Sega Master System II, released in 1990, is a redesigned and more affordable version of Sega’s original 8-bit console. With a compact form factor, simplified architecture, and built-in games like Alex Kidd in Miracle World or Sonic the Hedgehog, the Master System II introduced a whole new generation of players to Sega’s vibrant 8-bit world.
Although created as a cost-effective model, it quickly became one of the most recognisable consoles in Europe, Australia, and Brazil — and today stands as a nostalgic favourite among retro collectors.
📘 Introduction
By 1990, Sega wanted to revitalise its 8-bit lineup with an updated model that was cheaper to manufacture and easier for families to pick up and play. The Master System II removed several features of the original console but gained:
-
Lower price
-
Built-in game
-
Smaller, more modern look
The result was a system that became extremely popular in European markets and helped maintain Sega’s strong presence even during the 16-bit Mega Drive era.
🎨 Compact & Stylish Redesign
The Master System II features:
-
A small, rounded, minimalist shell
-
Grey/red accents and Sega branding
-
No more front buttons — just Power and Reset
-
Rear cartridge slot for simpler internal design
This streamlined approach reduced manufacturing costs while giving the system a sleek, modern appearance.
⚙️ Simplified Hardware
To make the system more affordable, Sega removed:
-
The card slot (no more Sega My Card support)
-
Expansion port
-
AV port on most models (RF-only output for early units)
The core 8-bit hardware remained the same as the Master System I:
-
Zilog Z80 CPU @ 3.58 MHz
-
256×192 resolution, 32 on-screen colours
-
Strong sprite handling
-
PSG audio chip
Despite these simplifications, game compatibility remained excellent.
🎮 Built-In Games — A Sega Tradition
One of the biggest appeals of the Master System II was its built-in game. Depending on the model, you’ll find:
1. Alex Kidd in Miracle World
The most iconic inclusion — a full platforming adventure beloved by Sega fans.
2. Sonic the Hedgehog (8-bit)
Later revisions replaced Alex Kidd with Sonic, making the system instantly recognisable to the 1990s audience.
3. Snail Maze (hidden)
On very early units, pressing Up + Button 1 + Power activated the secret Snail Maze game.
