Torneko no Daiboken: Fushigi no Dungeon (translating as “Torneko’s Great Adventure: Mystery Dungeon“) is the first game in the Mystery Dungeon series from Chunsoft, the developer known for creating the Dragon Quest series. It is a ‘Roguelike‘ dungeon-crawler, with randomised maze-like dungeons and was first released in 1993.
Developed by Chunsoft and released for the Famicom by Enix in 1986, Dragon Quest was a landmark moment in video game history.
Dragon Warrior is the American NES release of Dragon Quest, translated into English and tweaked here and there (I say “tweaked here and there” but the US version had battery back-up saves and the Japanese version used password saves, so there was a big difference there), and released by Nintendo in 1989. These grabs are from the later North American English language release.
