859 | help | |
860 | The Maple Bus is SEGA's serial communication bus for peripherals | |
861 | on the Dreamcast. Without this bus support you won't be able to | |
862 | get your Dreamcast keyboard etc to work, so most users | |
863 | probably want to say 'Y' here, unless you are only using the | |
864 | Dreamcast with a serial line terminal or a remote network | |
865 | connection. | |
