Sega Genesis prices, all games & how to spot a fake

A Sega action role-playing game that stayed in Japan, and a fairly cheap Mega Drive cart.

Tōgi Ō: King Colossus is an action role-playing game developed and published by Sega for the Mega Drive. It came out only in Japan, on 26 June 1992, and was not localized; an English fan translation appeared in 2006.

Before you buy

Among Japan-only carts it sits below the middle. A Japanese cartridge is a different shape and does not fit a Western console without an adapter or removing two plastic tabs in its slot. The cartridge saves to a battery inside it, so check that a save holds; a replaced battery is a normal repair.
