 Three additional system models were created by other electronics companies . Working with Sega Enterprises , JVC released the Wondermega on April 1 , 1992 , in Japan , at an initial retail price of ¥ 82 @,@ 800 ( or US $ 620 ) . The system was later redesigned by JVC and released as the X 'Eye in North America in September 1994 . Designed by JVC to be a Genesis and Sega CD combination with high quality audio , the Wondermega 's high price kept it out of the hands of average consumers . Likewise was the case with the Pioneer LaserActive , which was also an add @-@ on that required an attachment developed by Sega , known as the Mega @-@ LD pack , in order to play Genesis and Sega CD games . Though the LaserActive , developed by Pioneer Corporation , was lined up to compete with the 3DO Interactive Multiplayer , the combined system and Mega @-@ LD pack retailed at nearly $ 1600 , becoming a very expensive option for Sega CD players . Aiwa also released the CSD @-@ GM1 , a combination Genesis / Sega CD unit built into a boombox .
