1. What Was the SEGA CD?

The SEGA CD (known as the Mega-CD in Japan and Europe) was a CD-ROM add-on for the SEGA Genesis / Mega Drive, released in 1991 (Japan) and 1992 (US/EU). It aimed to expand the console’s capabilities with higher-quality audio, full-motion video (FMV), and more storage space for larger, multimedia-rich games.

It was SEGA’s bold attempt to push console gaming into the future — and although it had mixed success, it remains one of the most iconic pieces of retro tech history.

4. Legacy and Cultural Impact
