Display scale factor (default 10)

Path to ROM (mandatory)
The original CHIP-8 had a 64x32 pixel display, which is too small for modern
screens. The optional scaleFactor argument can be used to upscale it to a
more sensible size. With the default value of 10 the emulated display will have
a size of 640x320 pixels and each CHIP-8 pixel will be rendered as 10x10px
rectangle.
Keyboard mapping
CHIP-8 systems used a hexadecimal keyboard with the layout shown on the left. This is mapped to the physical keyboard as shown on the right.

So to get "deadbeef" inside the emulator you'd have to type "rfzrcffv".
