The Wondermega was released in 1992 as a joint development by Sega and JVC. It is similar to the Multi-Mega, being a combination of a Mega Drive and Mega CD, but with the added ability to function as a karaoke machine and improved sound thanks to JVC's new DSP. The system shipped with four karaoke programs and a compilation CD of four games. Two microphones can be connected to the system so users can sing along with CDs, or, thanks to a button on the machine, the CDs vocals can be muted allowing you to sing with just the music as a backing track.
In 1993 the WonderMIDI package was released. This allowed users to connect a MIDI keyboard the Wondermega to create sound effects and music, and included instructional software which could help people learn to play the piano. 1993 also saw a re-release of the system, with several small changes designed to reduce cost.
