Ultraman (ウルトラマン, Urutoraman?) is a Japanese Tokusatsu television series that first aired in 1966. Ultraman is a follow-up to the television series Ultra Q, though not technically a sequel or spin-off. The show was produced by the Tsuburaya Productions, and was broadcast on Tokyo Broadcasting System (TBS) from July 17, 1966 to April 9, 1967, with a total of 39 episodes (40, counting the pre-premiere special that aired on July 10, 1966). Although Ultraman is the first series to feature an Ultra-Crusader, it is actually the second show in the Ultra Series. Ultra Q was the first. In fact, Ultraman opens with the Ultra Q logo exploding into the Ultraman logo. Ultraman ultimately became a major pop culture phenomenon in Japan. The show's success spawned dozens of sequels, spin-offs, imitators, parodies and remakes. To distinguish him from subsequent characters named "Ultraman", Ultraman is referred to as the Original Ultraman (初代ウルトラマン, Shodai Urutoraman?), the First Ultraman, or Ultraman Hayata; this last is a reference to his host's surname.

Uncharted Waters, normally released as Daikoukai Jidai (大航海時代?), is a popular Japanese video game series produced by Koei under its "Rekoeition" brand. It is a simulation and role-playing video game series dealing with sailing and trading, themed around the Age of Discovery. In the games, the player takes up the role of a captain (or commodore in some translations) and manages a seagoing fleet to participate in trades, privateering, treasure hunting, exploration, and plain piracy. Even though the series is largely open-ended, there is still a loose plot which requires the player to follow certain paths, and deviating from these paths may stall the progress of the story. In East Asia, the series has a large cult following, but it has not received much recognition outside the region. However, it has been compared to the earlier Sid Meier's Pirates! in gameplay and theme.

This game is perhaps the most famous of the series. Even though an English version exists, it still has not managed to achieve the mainstream popularity Pirates! had. There is only a relatively small following outside East Asia.

Undeadline (アンデッドライン; also referred to as Undead Line) is a 1989 shoot-'em-up for the MSX2 by T&E Soft.

In short, Eggman wants to destroy Sonic, and, well, Sonic just won't have that, and it's up to you to stop him.Currently, I have GHZ and the first two acts of MZ finished in time for the contest. I kinda rushed it to the finish so you should expect some anomalies here and there.This hack made by Bagumba

Valis (ヴァリス Varisu?) is a Japanese platform game series developed by Telenet Japan. The original game was developed in 1986 for the MSX, and its popularity has spanned four sequels, a spin-off, and remakes across several platforms, notably the TurboGrafx-16 and Sega Mega Drive until the early 1990s, when it was quietly retired. The Mega Drive/Genesis entries were all published in North America by Renovation Products. Later, Telenet sold the series' rights to a company known as Eants, which re-tooled the series as hentai games[1] after Telenet shut down in 2007. The series has formed two Mobile Phone games released by Bandai Namco Games in Japan and a manga by Kill Time Communications. The Valis games (as they were known in America) tell the story of Yūko Asō (麻生 優子 Asō Yūko?), a schoolgirl in late 1980s Japan who is fated to protect three different realms – our own Earth, the land of spirits, and Vecanti (ヴェカンティ Vekanti?), the Dream World – by wielding a mystical sword known as Valis.

Valis III (ヴァリスⅢ, Varisu Surī?) is an action-platformer video game developed by Telenet Japan and originally released for the PC Engine Super CD-ROM² on September 7, 1990 in Japan.

It is the third game in the Mugen Senshi Valis series and once again features Yūko Asou (麻生 優子, Asou Yūko?) as the lead character. She is also joined by her twin sister, Valna, and a young Vecanti warrior named Cham who are playable characters.

Valis: The Fantasm Soldier II (夢幻戦士 ヴァリスⅡ Mugen Senshi: Varisu Tsū?), which had a remake done with super deformed characters and released as SD Valis (SDヴァリス Esu Dī Varisu?) on the Japanese Mega Drive and Syd of Valis – a translation mistake as SD means super deformed – on the North American Sega Genesis, is the second title in the Mugen Senshi Valis video game series. Like its predecessor, it is an action platformer.
