[i]Dino Island ~Yokoku-hen~[/i] was released in December 1996, roughly a month and a half before the full game as a paid demo advertising it. It cost one third of the full game's price and featured a short story (though calling it that is a stretch) where Emiri Itou and her twin sister Ange introduce the player to the island and game's setting, including small bits that [i]would be[/i] present in the full game as well but slightly reframed for the demo.
The demo is fully voiced by the cast but, unlike the full game which was a multiple choice digital manga animated without use of video codecs and with multiple endings, the experience is entirely non-interactive. If you played or know about [i]Yumimi Mix[/i] by the same authors, originally released in 1993 on Sega's Mega CD addon and later ported to Fujitsu's FM Towns, Sega Saturn and, later still, to Windows, the formula is [i]exactly[/i] the same.
The game's CD-ROM also had some bonuses: a game opening karaoke mode with an ability to adjust volume of BGM and vocals (they're actually stored in the same audio track, program running on the Saturn only sets the volume for left and right channels) and an art viewer.
Like the full game, half of the manual (which was, as is typical for JP Sega Saturn releases, a jewel case booklet that doubled as a cover) also features a short manga lovingly drawn by Izumi Takemoto, the mangaka responsible for drawing the game and plot.
Also, the humorous audio track serving as a warning not to play the game's disc on a hi-fi is also different from the one used in the full game.
