Mouse
An official computer-style pointing device for the Sega Dreamcast. Used in some games and quite useful for internet browsers.
Description
The Dreamcast’s Mouse connects via the console’s controller port and functions like a regular computer mouse. It translates movement into precise on‑screen cursor control, offering an alternative to analogue stick input. The design mirrors contemporary PC mice, with two buttons, a scroll wheel, a side button, and its casing matches the Dreamcast’s white aesthetic. Sega marketed it as part of the Dreamcast’s broader push toward PC‑style functionality, alongside the Keyboard and Broadband Adapter.
It is compatible software such as Quake III Arena, Unreal Tournament, and Phantasy Star Online. It is also supported by Sega’s web browser discs like the Dream Passport and DreamKey, allowing users to navigate the console’s online services with greater ease than the standard controller. In shooters it enables faster aim and strafing, while in online applications it provides familiar point‑and‑click navigation. The model was mostly universally across all markets. In Japan there were revised models released that dropped the side/back button, and later provided alternate colour options.
At the time it was a niche accessory that only a few purchased. Although I had no plans to use the Dreamcast as a primary internet access device, I appreciated the additional control method is provided in some software. It was one of the more practical peripherals in the Dreamcast’s extensive accessory catalogue, though its usefulness was constrained by the small library of compatible software.
