LaserActive

PAC modules Pioneer released several expansion modules, known as "PACs," which enabled the LaserActive to play software from other platforms and expand its capabilities. In each case, the Japanese model number is listed first, followed by the North American version. ;Mega-LD PAC (PAC-S1 / PAC-S10) :Developed with Sega, this PAC enabled support for Mega-LD software as well as standard Genesis cartridges, Sega CD discs, and CD+G discs. It included a LaserActive-branded 6-button Genesis controller (model CPD-S1) and retailed for . It was the most widely adopted module among LaserActive owners. ;LD-ROM² PAC (PAC-N1 / PAC-N10) :Developed with NEC, this PAC added support for LD-ROM² titles, along with HuCard cartridges, CD-ROM² discs, and CD+G discs. The Japanese model could also play Arcade CD-ROM² titles using an Arcade Card Duo. Like the Sega module, it sold for and included a branded Turbo Pad (CPD-N1/CPD-N10). NEC also released a version in their branding called the PC Engine PAC (model PCE-LP1). Due to the TurboGrafx-16's limited success in North America, the PAC-N10 is significantly rarer than its Sega counterpart. ;Karaoke PAC (PAC-K1) :This PAC enabled playback of the LD-ROM-based LaserKaraoke (LD-G) discs. It featured two microphone inputs with individual volume and tone controls. Retail price was approximately . A separate goggle adapter (model ADP-1) allowed one or two goggles to connect to the CLD-A100. ==Software==

The LaserActive uses a unique disc format called LD-ROM (LaserDisc Read-Only Memory). Like the LV-ROM format on which it is based, the LD-ROM is an optical disc format that can store analog video, analog audio, and computer files (in a file system) on the same side of a disc. LD-ROMs do not use the same file system as LV-ROMs, however; also, an LD-ROM can store up to 540 megabytes of file data, compared with LV-ROM's 324. An LD-ROM can store up to 60 minutes of analog audio and video alongside the digital file system. The tables below list 31 software titles released on LD-ROM for the LaserActive; of these, 13 were released only in Japan. 23 of the 31 were made for the Mega LD PAC, and 15 were made for the LD-ROM² PAC. Only a handful of titles were released in both formats. One additional title listed below, Myst, was never officially released for the LaserActive. Circa 1995, a game developer named Brian Rice (of Brian Rice Inc.) was leading the conversion of Myst to Mega LD. Conversion was almost entirely complete, and the game was to be published by Sunsoft. But, Rice encountered a major problem. Normally, an animated dissolve or wipe effect transitioned the view when the player moved between scenes in the game. Each transition animation had six frames. Yet in some circumstances, the animation did not stop at the sixth frame, but continued to shift the player's view to other scenes in the game. Rice ascribed the runaway animation to a bug in the LaserActive hardware. Development and publication were scrapped. Another unreleased game, called Steel Driver, is rumored to exist. ==Contemporary devices==

In the early 1990s, a number of consumer electronics manufacturers designed converged devices around CD-ROM technology. At the time, CD-ROM systems were expensive. The LaserActive was one of several multipurpose, multi-format, upmarket home entertainment systems with software stored on optical discs. These systems were premised on early conceptions of multimedia entertainment. Some comparable systems are the Commodore CDTV, Philips CD-i, 3DO Interactive Multiplayer, and Tandy Video Information System. ==Reception==

Computer Gaming World in January 1994 stated that although LaserActive was "a better product in many ways" than 3DO, it lacked software and the NEC and Sega control packs were too expensive. ==See also==
