Mega-CD II
The Mega-CD II was released alongside the Mega Drive II has a cost-reduced option that better suited the aesthetic changes made to the Mega Drive II. The console was released on the 23rd of April 1993 in Japan, June 1993 in North America and August 1993 in Europe. This version of the system features a top-loading mechanism as opposed to the motorised CD tray of the original design. The entire base of the unit extends to the left so that a Mega Drive can be securely fastened on top of it. The Mega-CD II can connect to an original Mega Drive using an additional plastic spacer which was also supplied with the machine. This is because an original Mega Drive has a wider footprint than a Mega Drive II. Alongside the console’s new aesthetic design, a new version of the Mega-CD BIOS is included, numbered v2.00. This features a new user interface design that functions largely the same as the original.
