Controllers
The Dreamcast controller is central to the experience, and a few details are worth knowing as you set up a modded console — particularly because the controller is where your saves live.
The VMU connection
Each controller has expansion slots, and the most important accessory is the VMU, the Visual Memory Unit. This little memory card slots into the controller and stores your game saves on its own small screen. Modding does not change how saves work, but it makes backing them up more valuable than ever.
Wired and the rumble pack
Standard Dreamcast controllers are wired. A second expansion slot can hold the Jump Pack for rumble feedback. Both work normally on a modded console; an ODE changes how discs are read, not how controllers behave.
Navigating homebrew
Loaders such as DreamShell and ODE menus are driven entirely by the controller, so a fully working pad with responsive buttons and a reliable d-pad makes browsing your library much more pleasant.
Care for your VMU
The VMU's internal clock battery drains, and a dead battery can lose date settings and, over time, threaten saved data. Back up your saves regularly and keep the VMU charged through normal play.
If you intend to manage saves seriously, see the DreamShell page, which can read and write VMU data alongside loading games.
