Sometimes contain different ROM versions. Player models and versions within each brand. There are several brands of CD-i players, and typically multiple This article and I will ignore such ROMs below. May need these dumps now or in the future, but it is not relevant to the rest of Or a special test or manufacturing mode needs to be used in order to read outįortunately, CD-i Emulator does not use low-level emulationįor these chips and hence does not need dumps of their ROMs. Dumping this can be complex, in some cases the chips need to be “decapped” In addition to the CD-i system ROMs, which are accessibleįrom the main 68000 CPU, CD-i players and digital video cartridges oftenĬontain microcontroller and/or signal processing chips that have their own ROM.

Sony IVO-V11 player with service switch and serial cable Opening the player and doing a little soldering. To be accessed directly from the system board which in this case does mean
They do have a service port that supports serial communication although it needs Players do not have a regular serial port accessible from the outside. The system ROMs of all CD-i players encountered so far canīe dumped this way, with one exception: the Sony IVO-V10/V11 players. Player has no such download function, a “CD-i stub ” disc can be used Scanned for ROMs and their contents can be dumped via the serial port. Small “CD-i Stub ” program into the CD-i player so that memory can be ROM contents could also be dumped over the audio or video outputs but that hasĮarly 2005 I wrote a program called “CD-i Link ” that uses the built-in download function of most CD-i players to download a This is typically done over the serial port as mostĬonsumer players have no other easily accessible output port (theoretically the Inside the CD-i player (that is after all their primary function), so they canĪlso be dumped using software. However, the contents of these ROMs are also accessible from Means opening the player and often requires desoldering the ROM chip. Happen the ROM chip typically needs to be removed from the CD-i player, which These devices can be custom made hardware,īut an off-the-shelf EPROM programmer device can also be used. Īll CD-i system ROMs are standard ROM chips that can be

These ROMs, which must be obtained from the hardware using a pro cess called “ dumping ”. Hardware, which in this case includes IMPEG digital video.Ī low-level CD-i emulator needs access to the contents of
The CD-i 615 and CD-i 670 use another extension board whichĪlso contains 512KB of ROM with support modules for their additional Other hardware on the board, and it is mostly filled. In contrast to this, the CD-i 605 extension board containsĥ12KB of additional ROM to support the Ethernet and SCSI controllers and Extension boardsįor this unit have sockets for additional ROM chips but I have never seen them For example, the CD-i 182 unit contains an additional 64KB of ROM withĭrivers for the floppy drives and other hardware in this unit. Professional or authoring players typically have other additional ROMs, usually located on some kind of (removable) extensionīoard. Some cartridge versions also contain some utility Little over half of this ROM is typically used, it varies somewhat

ROM with CD-RTOS file managers and drivers to support the MPEG playbackįunctions. Most CD-i Digital Video Cartridges (DVCs) contain 128KB of additional ROM is again filled with code and resources for the player shell.

The core system software takes less then 200KB of this, the remainder of the Have 1MB of system ROM, although only a little over 835KB of that is used. Notable exceptions to this are the Sony IVO players which Niceties such as the CD+Graphics decoder “ cdgr ” or the Service Shell “sv ” have been omitted.
#CD I EMULATOR WITH MAME FULL#
On some of the later Philips players the system ROM is so full that Resources (e.g., images, fonts) for the player shell and usually some utility Typically takes less than half of the ROM, the rest is taken up by code and Player hardware, as well as system startup programs. Including the OS-9 kernel, CD‑RTOS file managers, drivers for the specific CD-i This system ROM contains the core system software The typical CD-i player contains 512KB of system ROM which contains the CD-RTOS operating system based on Microware PCI/ISA CD-i boards from I2m / Philips that have their system software loaded (ROM) chips inside the CD-i player the only known exceptions to this are the The CD-i system software is typically stored in read-only memory This means that to perform theirĮmulation function they need copies of this software. Low-level emulation for the system software. Most currently existing CD-i emulators use so-called
