Philips CD-i

The  is a multimedia CD player developed by Royal Philips Electronics and released in North America and Europe. At the time of its inception, the CD-i was not envisioned as a game console, being designed for general multimedia purposes based around various capabilities of the format (including music, home video, computing, and educational services); the inclusion of video game support was by comparison an afterthought. Despite this, however, it primarily maintains a reputation as a video game console, in part because of the near-unanimous negative reception towards many of its most prominent titles, including ones based around Nintendo's IPs. The CD-i was originally released in 1991 at the price of $700 in the United States, and it was released in both Japan and Europe the following year; releasing nine days before the Japanese launch of the competing Mega-CD (later released in the US as the Sega CD), it was the second video game system to support CD-based games, following the 1988 launch of the PC Engine CD-ROM² (later released internationally as the TurboGrafx-CD).

Nintendo originally made a deal with Philips to develop an add-on for the Super Nintendo Entertainment System to allow it to play CD-based games, after a similar deal with had fallen through. The project was later aborted, but in exchange for their involvement, Philips was given the license to use five of Nintendo's characters in games.

Using Nintendo's licenses, Philips released three games for The Legend of Zelda series, one for the Mario franchise (two more were planned but were canceled), and a version of . The The Legend of Zelda and Mario games received very bad reception, and the system generally sold poorly after 1994. Common criticisms of the CD-i were its price, the graphical quality of its games (compared to the Super Nintendo or ), its poor library of games (including an influx of, pornographic games, and ), and the controls. Special criticism was used for the controllers of the CD-i. There were four main models of the controllers of the CD-i: a basic controller with three buttons and a D-pad (the console used only two buttons; the third was mapped to the first two buttons being pressed simultaneously), another that resembled a spoon, another similar to the first one but with a protruding stick on top, and one resembling a TV remote, which was the one that came standard with all the consoles. Also in the vein of a remote control, the latter was wireless, communicating with the CD-i using an infrared sensor; because a connection between the infrared ports had to be continuously maintained, moving the controller out of alignment or placing another object between it and the console would cause it to become nonfunctional until the connection is restored. None of the controllers featured a Start button.

In 1998, Philips announced that the CD-i had been discontinued, following low consumer adoption caused by a combination of its high price point, unreliable controls, poor video game library, and pressure from competing devices in every field it tried to tap into, both within and outside video game-related niches.

Unannounced port of Donkey Kong '94
A port of Donkey Kong '94 was apparently in development for the system. His character was announced for an appearance in the console in a 1991 advert. The only known report of it is the LinkedIn resume of programmer Adrian Jackson-Jones, which states the Philips CD-i port of the game was in development during the 1992-1993 period at RSP. Jackson-Jones "designed and implemented the game engine" for the project.
