You can now run Windows Vista on the PS3. More accurately, you can emulate Windows Vista on the PS3; “now” is also somewhat inaccurate, as the emulation is so slow it takes some 25 minutes for the operating system to boot up.
It works by running Qemu on Linux on the PS3, then running Vista in Qemu. The whole process takes about a day to get up and running.
Reminds me of kids trying to get Windows to run on Xbox1 using Bochs.
