What hidden applications are burnt into the CD-i players system ROM?
Most CD-i players have additional programs and other modules stored in ROM that you can check out using a terminal connection. If a Digital Video cartridge is installed, which contains its own ROM, even more modules will be available. One of the things I discovered using some of the early CD-i players based on the Mini-MMC board (CDI 910, CDI 205 and CDI 220/00) is that a service maintenance tool is available in ROM. Just start it by typing sv at the prompt (make sure the player shell and other applications have been terminated, since this program needs the CD-i’s video display). A screen will show up with a nice cursor in the form of a open end fork! You can check system functions and audio and video features. This program is probably used in the factory to test a player. It’s realy amazing to see a program appear on your screen that’s litteraly hidden in the player! Other things that are known to be available in the ROM of the Digital Video cartridge are tools to play a Video-CD usin
