You have to select 64 from the Mode field, then select 32 again to make the right value appear.Īs an exercise, the hex value eddda025 should result in the output "fdivs. Once you enter these values into the form and paste the hex value into the bottom left text field, you will see an instruction on the right. Then push the read button labelled "Platform: i386". You would push the blue "START DISASSEMBLING!" button. This hex value can be translated into a PowerPC instruction name using this website. The text "previous insn" will tell you the instruction that failed, but not in a easy to understand way. If a problem happens during testing the test will end and you well see information on registers and info on the faulting instruction. What happens next is the two risu instances will talk to each other to see how each executed instruction's output looks like. Push the start button on both the PowerPC Macintosh and the QEMU VM. On the QEMU VM select "host" in the "Test" section.Įnter the IP address you see on the master window into the same field in the host window. An ip address appears in the ip address field. On the PowerPC Macintosh select "master" in the "Test" section. Type "python frontend.py", then push the return key. The following instructions should be followed on both the PowerPC Macintosh and on the QEMU VM:ģ. Once this process is done copy the file ppc.out to the risu folder in both the PowerPC Macintosh and the QEMU VM. An x86 Macintosh will be fine.)Įnter in the "Number:" field the number of instructions you wish to test. I suggest generating it on a newer computer. (Note: this file can take some time to generate. #RUN POWER PC EMULATOR ON NEWER MAC MAC OS X#This other computer could be a Windows PC.Ĭopy the risu folder on both a PowerPC Macintosh running Mac OS X and a QEMU VM that is also running Mac OS X. You just need a computer that is on the same network as the PowerPC Macintosh and is running Mac OS X in qemu-system-ppc. You need a real PowerPC Macintosh to do the comparison, but you don't need an x86 Macintosh. Both the x86 and PowerPC Macintoshes were on the same wifi network. My setup was an x86 Macintosh running a QEMU VM that was running Mac OS 10.4 and a PowerPC Macintosh also running Mac OS 10.4.
