PHP Chip-8 Emulator

I don't know how many turing mashines deep this is but here is a Chip8 Emulator written in PHP.

Built on PHP-GLFW and the VISU framework.

Features

It runs Chip8 ROMs!
This is obvious, but the moment it started working was magical to me, so I'm putting it here.
Debugger
You can step through the code and see the state of the registers and memory.
Press space to pause or hit the Pause button.
Drag and Drop
As seen in the demo, you can simply drag and drop your ROMs onto the emulator.
Fullscreen mode
If you don't care for all the debugging stuff, you can simply go fullscreen and enjoy the game.
Virtual Keyboard
You can use the keyboard in the GUI or use the keybindings:

1 2 3 C -> 1 2 3 4

4 5 6 D -> q w e r

7 8 9 E -> a s d f

A 0 B F -> y x c v
Ghosting Effect
I'm honestly not very knowledgeable about old hardware, but I'm assuming that the old CRTs would take some time for the phosphor to fade out. I tried to emulate this effect by adding a ghosting effect to the display, as the flickering otherwise is quite unpleasant.
You can change the strength of the effect.
CRT Effect
Some might hate this effect; I like it, but of course, you can turn it off.
GUI! The GUI is created using an immediate mode style of drawing. You get results really quickly, the code is really ugly and performance is really not great.

What is this?
It is a Chip8 Emulator written in PHP.
Can I use it in Production?
Of course! Its beyond my understanding why you would want to do that, but sure go for it!
Why did you make this?
Yes!
Thats not a real answer
Yes!
Is this a real FAQ?
Yes!
Yes!
No!
