XRoar is a Dragon and Tandy CoCo emulator.

The DS port is coming along. This version features interface for input configuration and snapshot saving. It is built against the most recent CVS release of libfat, so supports DLDI patching (not required for DS-Xtreme, of course). Sound is present, but is not synchronised with the rest of the emulation yet, so tends to be very scratchy. No input configuration is stored anywhere yet. ROMs should sit in fat:/dragon/.
