Extra broadcast information
* 1995/10/ 8 * ☆急告！！「天地創造」オンエア！ 緊急情報が飛び込んできた。 エニックスの新ソフト「天地創造」のデモ・バージョンが特別オンエアされることに決定したのだ。 １０月１１日（水）から１０月１７日（火）の２１：３０～２２：００のゲームリクエストアワーの時間帯に、緊急割り込みオンエアされる。 見逃すな！
The demo version is undumped and hence unknown what exactly it contains or how far it goes.
The article below is vague about the demo details, mentioning the opening and reviving scenes implying more than the first dungeon maybe even the complete underworld section?
An article in Famitsu (Issue 10 and 17, Nov 1995, p. 195) is mentioning the broadcast:
(Title) Provided by the satellite, a drama of the riviving world!
ENIX provides a big autumn present for all Satellaview users! A demo version of "Tenchi Sozo" is now being broadcasted over Super Famicom Hour. Unfortunately, because it is a monumental RPG that occupies 32M bits, the complete playable data cannot be distributed. But it can show you cool reviving scenes and the opening demo. For those who is interested in the game, informed by magazines, don't miss it.
Other than "Tenchi Sozo" demo, a trial version of "Maho Jin Guruguru" and a demo of "Dragon Quest 6" will be broadcasted shortly. Look forward to it!
