I have not been playing p99 lately. I did get it to work decently. VMWare Fusion is free for personal use. Use that and install Windows ARM. When you create a VM for the first time in VMWare Fusion it asks if you want to download and install Windows ARM. Once the VM is up and running. Install the VMWare guest tools and reboot. Then copy p99 folder over to the VM.
