Installing Windows XP on an iPhone
The video demonstrates how to install Windows XP on an iPhone using the UTM app, which is an emulator that allows users to run x86 operating systems on their iOS devices. The host uses the UTM app to create a virtual machine, downloads a Windows XP ISO, and installs it on the virtual machine. They also try to run Half-Life on the emulated Windows XP, which works, albeit with some performance issues.
