The Philips CD-i is an entertainment system made by electronics/health care company Philips in 1991.
The CD-i was not originally designed as a console or even to play games but rather as a general multimedia package that can run educational software, play music and video CDs (with a Digital Media Card, also required for a few games that used FMV). The system was a marketing failure, and today is infamously known as being a console that featured laughably terrible licensed games featuring Nintendo properties.
Emulation on the CD-i is still in early progress. While games such as Hotel Mario and the two Zelda side scrolling games work, many of its library however do not especially the Digital Media Card games.
MAME runs the CD-i and some games work but however has problems in terms of progress so don't except much more progress for a while.
