# 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](http://github.com/mario-deluna/php-glfw) and the [VISU](https://github.com/phpgl/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.
