About Galactic Protector

Galactic Protector is a Sega Master System shoot-'em-up game developed and published by Sega. It stars Opa Opa of Fantasy Zone and Zillion fame, who must save various planets from enemies and debris hurtling towards them. The game is built specifically for the Paddle Control, and therefore cannot be played on a standard Master System Control Pad. This also makes emulating the game tricky. Like the Paddle Control itself, Galactic Protector was not released outside of Japan. It was released as part of the Fantasy Zone Complete Collection for the PlayStation 2, also Japan only.

Sega Master System prices, all games & how to spot a fake

A Japan-only Sega cart built around a special controller, priced above the middle of the Japanese carts.

Galactic Protector was developed and published by Sega and released in Japan on 21 February 1988. It was made for the Japan-only Paddle Control, according to the game booklet and Sega catalogue.

Before you buy

The Paddle Control is required, so budget for the controller as well as the cart. A Japanese cart is a different, smaller shape and does not fit a Western console without an adapter. Loose, it is priced above the middle of the Japanese-only carts, and the look-alike risk is low.
