'''CD-I''' ('''Compact Disc Interactive'''), is a disk format and media player developed and released by [[wikipedia:Philips|Philips]] in 1988. The first player aimed for home market was released Main system ran on December 3, 1991, Microware [[wikipedia:OS-9|OS-9]] and had a Philips SCC68070 CPU at 15.5 MHz with an initial price 1MB of {{Inflation|USD|799|1991}}RAM. Some Third-Party manufacturers made their own media players based on the CD-I format & technology.

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. 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. CD-I is mainly known nowadays for having games based on Nintendo [[wikipedia:Intellectual property|IP]], 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 Emulator]]: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 67, this will be at 20242025/01/01. 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>

As of April 2023 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>.
