}}The '''Compact Disc Interactive''' ('''CD-i'''), is an interactive multimedia CD player and format developed and released by [[wikipedia:Philips|Philips]] on December 3, 1991. It had a Philips SCC68070 CPU at 15.5 MHz with 1MB of RAM. Notably, it featured intellectual properties from Nintendo, such as Mario and Zelda, due to previously having tried to develop a CD add-on for the [[Super Nintendo emulators|SNES]]. Their takes on Nintendo intellectual property were so infamously terrible that you would be hard-pressed to find anyone who doesn't think of them when you mention the CD-i. However, there were a few cult classic games for the system.

'''CD-I''' ('''Compact Disc Interactive'''), is a disk format and media player developed and released by [[wikipedia:Philips|Philips]]. The Main system ran on Microware [[wikipedia:OS-9|OS-9]] and had a Philips SCC68070 CPU at 15.5 MHz with 1MB of RAM. Some Third-Party manufacturers made their own media players based on the CD-I format & technology.
 
−
 
−
The CD-I was never meant to be a video game console, it was designed to be a "Interactive Multimedia" CD player, an expensive toy that people with money don't mind buying, using it a few times and forgetting they even bought it when something new catches their attention. When the system started to show signs of being a major flop for Philips, they pivoted the direction of the CD-I into the uncharted territories of video games.
 
−
 
−
The CD-I is best known nowadays for being home to three [https://www.mobygames.com/game/21134/zelda-the-wand-of-gamelon/ particularly] [https://www.mobygames.com/game/21409/link-the-faces-of-evil/ notorious] [https://www.mobygames.com/game/21411/hotel-mario/ games] loosely based on Nintendo copyrights, which were mainly made possible by Philips's prior attempts to develop a CD add-on for the [[Super Nintendo emulators|SNES]]. Their takes on Nintendo intellectual property have earned so much infamy over the years that you would be hard-pressed to find anyone who doesn't immediately think of them whenever you mention the CD-i. However, there were a few cult classic games for the system as well.

:This [[multi-system emulators|multi-system emulator]] includes a driver for the CD-i, although support is incomplete as it still has no [[#Digital Video Cartridge|DVC emulation]].<ref>https://github.com/mamedev/mame/issues/1170</ref> Starting the game from disc is recommended; this can be done with the built-in frontend by picking the specific game or through a soft reset after mounting the disc. MAME is also currently the only program to provide CD-i emulation through a [[libretro]] core, which makes it the easiest and the most stable method of emulating the CD-i for now. Compared to CD-i Emulator 0.5.3 beta 4, MAME is generally easier to control and can better emulate the audio for some games.

:Has a driver for the CD-i but support is incomplete, as it still doesn't emulate the Digital Video Cartridge (DVC) as of March 2019.<ref>https://github.com/mamedev/mame/issues/1170</ref> That means games that require it like 7th Guest, Atlantis - The Last Resort, Creature Shock, Dragon's Lair and Lost Eden are unsupported.<ref>https://github.com/mamedev/mame/blob/master/hash/cdi.xml</ref> However, MAME is much easier to control, and its audio emulation is actually better than CD-i Emulator in some cases. Starting the game from disc is recommended; this can be done with the built-in frontend by picking the specific game or through a soft reset after mounting the disc. It also has a [[libretro]] core, which makes it the easiest and the most stable method of emulating the CD-i currently.

:An unofficial build of [[MESS]] from 2009 made by one of MAME's active developers, Haze. This build is named such that it only focuses on the CD-i. It uses a fixed game list, but it works better than the official MAME builds, especially with games like Zelda's Adventure for example. On the other hand, some games have more issues than they have on the official MAME build.

:A payware emulator. Was presumed inactive but got a new beta release in 2018, two years after the last release. Used to only have mouse movements for control, now has preliminary keyboard support. However, the keyboard control isn't great in some games. The beta has proof-of-concept emulation of the Gate Array MPEG Digital Video Cartridge (DVC) but compatibility may still be an issue [http://www.cdiemu.org/site/relnotes.htm].

:This emulator by CD-i Fan is currently closed-source donationware, with vague plans to move to [[Licensing#Open-core software|open-core]] at a future date.<ref>https://github.com/cdifan/cdiemu</ref> The public beta releases unfortunately handle free trial timing in a way that makes them unusable (without cracking, anyway) after set calendar dates; for the latest beta, 0.5.3 beta 7, this will be at 2025/01/01. The current betas do have proof-of-concept [[#Digital Video Cartridge|DVC emulation]], although compatibility may still be an issue.<ref>http://www.cdiemu.org/site/relnotes.htm</ref> Despite the long time between releases, this emulator is still in active development as of April 2023, with work being done on the next version (likely called 0.6) that reportedly supports most of the DVC games and also has several other improvements.<ref>https://www.theworldofcdi.com/cd-i-emulation/cd-i-emulator-053beta5-titles-compatibilities/</ref>

====Digital Video Cartridge====
 
−
The one and only expansion card officially sold for the CD-i was the '''MPEG Digital Video Cartridge''' (DVC), a hardware MPEG-1 video decoder which enabled CD-i Digital Video and [[wikipedia:Video CD|Video CD]] playback as well as enhanced FMV capabilities for games that support it (similar to the [[Sega_Saturn_emulators#Hardware_features_and_accessories|Sega Saturn's Video CD Card]]). As of January 2024 there is no emulator that fully supports the DVC, and several games that rely on MPEG-1 video decoding will be pretty much unplayable without that support. To know whether your chosen games require the DVC, either check the "DVC status" column of [[wikipedia:List of CD-i games#Games|Wikipedia's CD-i game list]], or check [https://github.com/mamedev/mame/blob/master/hash/cdi.xml MAME's CD-i hash list] for games where the list includes <code>&lt;sharedfeat name="compatibility" value="DVC" /&gt;</code>.
