Hydlide (ハイドライド, Haidoraido?) is a 1984 action role-playing video game developed and published by T&E Soft. It was originally released for the NEC PC-6001 and NEC PC-8801 computer in 1984, in Japan only; ports for the MSX, MSX2 (a separate port released on 3.5" floppy), FM-7 and NEC PC-9801 were released the following year. A Nintendo Famicom version was first released under the name Hydlide Special on March 18, 1986 in Japan; three years later, in June 1989, that version saw a North American release for the Nintendo Entertainment System by FCI, its title having been returned to simply Hydlide.

Hydlide 3: The Space Memories (ハイドライド３ 闇からの訪問者, Haidoraido 3: Yami Kara no Hōmonsha) is an action role-playing game developed by T&E Soft and released in 1987 for the MSX (and separately for MSX2) and NEC PC-88, 1989 for the Nintendo Famicom and Sega Mega Drive (under the title Super Hydlide), and 1990 for the Sharp X68000.

Hyper Sports, known in Japan as Hyper Olympic '84 (ハイパーオリンピック'84) is a video game published in 1984. It is the sequel to Konami's Track & Field and features seven all-new Olympic events. Like its predecessor, Hyper Sports featured two run buttons and one action button per player. Like its predecessor, the Japanese release of the game sported an official license for the 1984 Summer Olympics. While not quite achieving the commercial and critical success of Track and Field, Hyper Sports still proved to be very popular among gamers.
