Build and add ninja.dll: This is a commonly used hack by performance-tuning tools like Pulse, allowing CPU frequency adjustment without the need to install additional software. This update loads ninja.dll and sets the CPU's multiplier and pre-scaler to run at 130 MHz instead of the default 104 MHz. While further testing is recommended, it is expected to function reliably.
