Apparently you can run pretty much anything on a PS3. [mopx0] has managed to get Vista running on his PS3. He used Qemu 9.0.1 to install Vista on a PC. He says it takes “about a day or so”, after using Vlite to speed it up, so be patient. You then make an image of the install and copy it to your PS3. Don’t worry though, your hard work will be rewarded by a speedy 25 minute boot time when you’re done.
Even though it is extremely slow, to the point of being nearly unusable, its good to see people pushing the boundaries of our hardware’s intended use.
