Hi Jakub,
I too am interested in getting Sparc64 working in Qemu in order to
resurrect some old Solaris disk images I have here. Can you explain some
more about the debugging methods you are using to analyse the forth
dictionaries?
At the moment I am struggling in that when running Qemu with "-vnc :1"
on the command line, qemu-system-sparc64 simply hangs :(
Many thanks,
Mark.
