Here is the Developer release of DragonDC. Includes last Dreamcast port formed by binary and source.

DragonDC is a Dragon 32/64 & Tandy Color Computer emulator and is created on a preliminary port of Quzar, based on Ciaran Anscomb’s XRoar 0.11.

It needs a GUI like DCider urgently and a few adjustments. Works fine on all emus of DC. A good idea is to enable the GUI included with the XRoar orignal source code.
