Summary 07651: sos: Incorrect release year, company & game title
Description This rom should probably be listed as:
SOS Game, K.K. Tokki (Namco license) 1979

I am aware of the warpwarp.cpp comments: “Kaitei (and SOS) is developed by Kazuharu Yoshioka of K.K.Tokki (Universal Tokki). Namco acquired license for these games.”

This post will provide proof that the game was released in 1979 by K.K. Tokki, and that there is an undumped version that predates the Namco licensed rom in MAME. Attached to this post is a scan of 3 advertisements from Game Machine magazine that were published in late 1979. In all 3 ads the game title is always referred to as “SOS Game”.

If you look closely at the screen photo you can clearly read “K.K TOKKI SOS GAME”. I think the Gee Bee “cross” might be a reference to the cocktail table with the X pattern legs. This game was exclusively a conversion kit targeted at games with black & white CRTs. The pcb was available in 2 formats.

In the company name, Tokki is the pronunciation of the kanji that means “Specialized Equipment” & kabushiki kaisha, commonly abbreviated KK, is a type of company defined under the Companies Act of Japan. So the company can also be written as K.K. Tokki, or Universal Tokki Co., Ltd.

notes: The wikipedia page for this game incorrectly refers to Shinryaku as the name of the player’s ship. This is actually the Japanese word for invasion or raid. The goal of the game is to prevent 100 planes from invading, thus the word Shinryaku appears at the bottom of the screen next to the count of successful enemy planes.
