| 777 | help |
| 778 | The Maple Bus is SEGA's serial communication bus for peripherals |
| 779 | on the Dreamcast. Without this bus support you won't be able to |
| 780 | get your Dreamcast keyboard etc to work, so most users |
| 781 | probably want to say 'Y' here, unless you are only using the |
| 782 | Dreamcast with a serial line terminal or a remote network |
| 783 | connection. |
