CD-i member Mary Emma created this beautiful and handdrawn map of Tolemac, which is the overworld of Zelda's Adventure on CD-i. It is full of details and I've never seen anything like this before, except for the recreated overworld made by Shikotei, who extracted all the graphics of this game. You can check the similarities with his map via this link. (click on the image to see it in high resolution)
Zelda's Adventure on CD-i might be the only game that comes closest to an adventure game with RPG elements on the CD-i platform. It was produced by USA based company Viridis, in the end it was only released in Europe early 1996 (while it was copyrighted 1995 on the boxart, it was not available in the shops before February 1996)
