Sega released a combined, semi-portable Genesis/Sega CD unit, the Genesis CDX (marketed as the Multi-Mega in Europe). This unit retailed at $399.95 in the US; this was roughly $100 more than the individual Genesis and Sega CD units put together, as the Sega CD had been reduced to $229 half a year before. The CDX was bundled with Sonic CD, Sega Classics Arcade Collection, and the Sega CD version of Ecco the Dolphin. The CDX features a small LCD screen that, when the unit is used to play audio CDs, displays the current track being played. With this feature and the system's lightweight build (weighing two pounds), Sega marketed it in part as a portable CD player.
