In terms of trying to implement a cg6 buffer emulator for QEMU, would 
there be a problem with just studying the code to determine the 
behaviour of the hardware blitter? I expect it would be extremely 
unlikely that any direct code copying would take place with the 
exception of a few defined constants for programming the hardware.
