Log Message:
Update the Commander X16 emulator and ROM to verison R47.  This is a major
release with several features and fixes, including 65C816 CPU support in
the emulator and KERNAL.  Due to a change in the ROM signature location
(to avoid conflict with the 65C816 vector table), both the emulator and
ROM must be updated together, even if you don't intend to use 65C816
support in the emulator.
