Philips CD-i
Overview
The Philips CD-i application is an emulator for the Philips CD-i multimedia entertainment system.
Important
The Digital Video Cartridge (DVC) is not supported. The DVC was an optional hardware add-on for the Philips CD-i that provided MPEG-1 video decoding, enabling full-motion video (FMV) playback in supported titles. Games that require the DVC may fail to load entirely or will not display their video content correctly.
BIOS File
In addition to Philips CD-i disc images, a Philips CD-i BIOS file must be specified globally within the feed (See the Feed Properties Dialog and Philips CD-i Feed Properties sections).

Internal Save Memory
The Philips CD-i application supports persisting the console's internal save memory into the browser's local storage or optionally to cloud-based storage. The contents will be persisted to storage whenever the pause screen is displayed (or the game is exited). Therefore, the menu should be displayed periodically for games that support saving to memory to ensure the state is properly persisted.

to another Philips CD-i application (different emulator implementation) if it is determined to be a
more appropriate default.
