==TurboGrafx-CD and CD-ROM²==

:''[[Wikipedia:TurboGrafx-16#Add-ons|TurboGrafx-CD/CD-ROM² and Super CD-ROM²]]''

The System Card 1.0 was included with the launch shipments of the CD-ROM² Interface Unit in 1988 (which did not include the actual CD drive, by the way; that had to be bought separately. ''Altered Beast'' requires it as it hangs with the newer BIOS versions, and someone reported an unspecified problem with ''Populous'' as well.

The System Card 2.0 was included in later shipments of the CD-ROM² System sometime in 1989 (around the time they started selling the Interface Unit and CD drive as a set). It served as the basis for the TurboGrafx-CD BIOS, which features a different title screen to go along with the different naming of the platform and its add-on in the US. Unlike HuCards, CD-ROM² discs are all region-free.

The System Card 2.1, released in 1990 exclusively in Japan, was the first System Card that was sold as a standalone, intended to be a replacement for users who had their original System Cards lost or damaged. Its only new feature was its ability to auto-detect disc changes.

The System Card 3.0 was launched in Japan in 1991. It was initially available built-in with the PC Engine Duo, a model of the console with an integrated CD drive, but was quickly offered as an upgrade to owners of the original CD-ROM² System in the form of the Super System Card, and later as an updated model of the add-on itself known as the Super CD-ROM² unit. The later models of the Duo (Duo-R and Duo-RX) also have this BIOS built-in. Version 3.0 increases the amount of buffer RAM from 64KB to 256KB, hence the addition of the word Super. Games that required this BIOS, which are labelled Super CD-ROM² discs, will display an incompatibility notice when loaded on a prior System Card.

This BIOS was released in the US in 1992 and was similarly offered built-in with the Turbo Duo (the US version of the PC Engine Duo) or as an upgrade for the TurboGrafx-16/CD in the form of the Super System Card (which was available primarily as a mail order).

==Sega CD and Sega CD 32X==

:Sega Retro: [https://segaretro.org/Sega_Mega-CD Mega CD], [https://segaretro.org/Sega_32X 32X], [https://segaretro.org/Sega_Mega-CD_32X CD 32X].

The Sega Mega CD and Sega CD 32X were add-ons for the Sega Genesis that expanded its capabilities with Mega CD-ROM playback (It can also play Audio CDs and CD+G discs), enhanced processing power, and a limited library of CD-based games with 32X functionality.

*[https://old.reddit.com/r/emulation/comments/1ay6fm1/ares_v136_released/krslaki/ Ares supports CD+G images].

==Philips CD-i Player==

Using CD-i player, you are able to watch movies, concerts and music videos from a Video-CD using the [[CD-i_emulators#Digital Video Cartridge]] extension (DVC), watch your favourite photos on a Photo-CD, listen your best album from an Audio-CD, play and learn using a large list of CD-i titles including games, educational software and multimedia titles. You are also able to sing karaoke songs mostly through CD+Graphics. CD-BGM, CD-i Ready, CD-Text, CD-Midi and CD-i Bridge are some of the other formats supported by the system.[https://www.theworldofcdi.com/what-is-the-cd-i/]

==3DO CD Drive==

The 3DO Interactive Multiplayer features a proprietary double-speed CD-ROM drive capable of reading standard 3DO game discs, audio CDs, and CD+G discs. It also supports Video CDs via an [[3DO_emulators#Home_media_accessories|optional MPEG hardware module]]. Because the system lacks copy protection or regional lockout, it can read CD-Rs, though aging lasers can struggle with burned media.

==Atari Jaguar CD==

The [https://en.wikipedia.org/wiki/Atari_Jaguar_CD Atari Jaguar CD] peripheral has a double-speed (2×) drive and built-in VLM (Virtual Light Machine) software by Jeff Minter, using a spectrum analyzer for a sophisticated video light show for audio CDs.

*BigPEmu supports both Atari Jaguar CD images and Audio CDs, although for Audio CDs you need to use bios image.

==Saturn's CD Player==

Sega Saturn supports CD-ROM discs. Also supports Audio CD, CD+G and Photo CDs. You need [[Sega Saturn emulators#Video CD Card]] for VCDs. On top of that, later revisions of the Video CD Card negate the need for "[https://segaretro.org/Photo_CD_Operating_System Photo CD Operating System]" disc software by giving the Saturn native Photo CD support.

For a long time, the PS3's Blu-ray player was a versatile and powerful feature and considered the best of all time, and many people still use it for this purpose today. Featuring a slot-loading [[wikipedia:Blu-ray_Disc_recordable#Speed|2 × speed]] ([https://hexus.net/gaming/news/ps3/7715-developer-duplicates-data-due-slow-ps3-load-times/ 9 MB/second]) Blu-ray Disc drive for BD-ROM, PlayStation 2 format DVD-ROM, PlayStation 2 and PlayStation 1 format CD-ROM, BD-Video, DVD-Video and Audio CDs. Keep in mind that, [[wikipedia:PlayStation_3_models#Original_model|original models]] also supports SACD but this functionality was removed with [[wikipedia:PlayStation_3_models#Slim_model|Slim]] and [[wikipedia:PlayStation_3_models#Super_Slim_model|Superslim models]]. There is no support for VCDs or SVCDs [[PlayStation_2_emulators#DVD_player|just like prior generation]]. DVDi, DVDPG, BDPG and Blu-ray Interactive HD like [[Home_media_players#Interactive_media|interactive film/movie]] formats are supported.

Crucial to remember that disc images are only suitable for disc-based titles. '''PSN digital titles (PKG)''' are '''not compatible''' with disc image mounting, because they try to write data to read-only virtual directories → this will cause errors (see explanation [https://github.com/RPCS3/rpcs3/issues/4021#issuecomment-1904000715 here]).

==LaserActive's LD Player==

Pioneer LaserActive supports [[Home media players|Audio CD]], [[Home media players|Video CD]], [[Home media players|CD-G]], [[wikipedia:LV-ROM#LD-ROM|LD-ROM²]], [[Wikipedia:LaserDisc#LD-G|LD-G]] and [[Home media players|Laser Videodisc]]. Advanced features like frame-by-frame playback or enhanced karaoke modes (e.g., for CD+G, a related but distinct format) may require inserting a Sega PAC (S-10) or NEC PAC (N-10) for improved functionality during VCD viewing. Without the Sega PAC, the LaserActive can still play the audio portion of a CD+G disc as a standard audio CD, but it won't display the graphical content. The NEC PAC (N-10) doesn't add CD+G support in the same way, as its focus is on TurboGrafx-16/PC Engine compatibility. Unlike most optical-disc standards, LaserDisc is not fully digital, and instead requires the use of analog video signals. Use [[Ripping games#Analog|this section]] for more infomation about LD capture.

==PlayStation Portable's UMD Drive==

The physical UMD Drive utilizes a 660nm red laser mechanism to read dual-layer optical discs with a maximum capacity of 1.83 GB and a data transfer rate of up to 11 Mbps (1.375 MB/s). Aside from reading standard game data, the drive's firmware and hardware layers handle region coding and copyright protection, which dictates how the PSP separates game executables from multimedia content layers.

While "UMD Movie" was initially common, "UMD Video" evolved as a broader term for various video content (TV, documentaries), while UMD Music saw limited use. UMD-PG refers to interactive media specific to the PSP.

During the era of the PlayStation Portable (PSP), "UMD Movie" was more common as it represented the main function of the format but as UMD adoption expanded beyond movies and included other types of video content such as TV shows, music videos, and documentaries, "UMD Video" became a more generic term to encompass the full range of applications. While UMD primarily focused on movies and video content, there was also some limited use of the format for UMD Music. However, it wasn't nearly as widespread as movie or other UMD Video content. UMD-PG on the other hand stands for UMD-Players Game, and it was used for a unique type of [[Home_media_players#Interactive_media|interactive media]] released on UMDs for the PlayStation Portable (PSP).

*PPSSPP has no UMD Video or UMD-PG support at the moment: [https://github.com/hrydgard/ppsspp/issues/4902 UMD Movie request] and [https://github.com/hrydgard/ppsspp/issues/11662 UMD Video and UMD-PG request] for PPSSPP. According to hrydgard (PPSSPP dev): "If someone contributes support for UMD Video to PPSSPP, it will be accepted and merged. [https://discord.com/channels/293316141479362560/293316141479362560/1178765683304181909 However, it's unlikely to ever be my personal priority, for example, "I'm focused on the game-playing part. There are better ways to watch video".] See [https://www.ppsspp.org/docs/faq/ PPSSPP FAQ: Can PPSSPP play UMD video discs?] section.

*JPCSP has [https://github.com/jpcsp/jpcsp/issues?q=is%3Aissue%20state%3Aopen%20umd%20video%20 partial UMD Video support] ([https://github.com/jpcsp/jpcsp/issues/388#issuecomment-1300530907 demonstration]).
