Sega Saturn Floppy Disk Drive Information

The Sega Saturn Floppy Disk Drive (セガサターンフロッピーディスクドライブ) was an official add-on to the console that was planned from much earlier than it’s Summer 1996 release. Development kits for the console include documentation and libraries that are used by the accessory are included in the Sega Saturn’s BIOS. Despite this, the unit was released a year and a half after the console and not heavily supported or marketed by Sega themselves.

The Saturn FDD connects to the console in the rear extension port via the cable included with the device. It allowed operators to use MF2HD 3.5″ floppy disks that could hold up to 1.44MB of data. You can copy your system’s internal RAM or external RAM cart data to the format. Since the internal RAM size was 32k and the largest memory carts only held 512k, this was a large improvement in capacity.

A few games allowed you utilize your FDD, including Dezaemon 2 (デザエモン2) and Panzer Dragoon Saga (AZEL -パンツァードラグーンRPG-). The former allowed you to create your own shooting games and saved the data to disks. The latter allowed you to save your your games on the disks. Some resources incorrectly state that only the Japanese version of PDS is compatible, but that is not true.

Koei released the Sega Saturn-you Word Processor Set (セガサターン用ワープロセット) which utilized the Sega Saturn FDD to store data. The later version of the set, WorPro Keyboard Set (ワープロ・キーボードセット), was also compatible.
