# A CHIP-8 emulator written in C++
This project was done to learn how to write a simple emulator, get a bettter understanding of CPUs and to learn a bit of C++.
Because I wanted to display some debug information, I was forced to learn a bit of OpenGL (core mode), too.
I wrote a small "screen" framework for OpenGL. The CHIP-8 output, memory debugger and register debugger are all
seperate "screens", added to the OpenGL window by defining a simple grid layout. The grid layout is very naive,
but enough to be used by this application. It also includes a simple resource manager to load shaders and fonts.
The font class contains a method to render text and uses *stb_truetype* to create a bitmap of the font file.
This emulator should run cross platform. Use CMAKE to compile it and run it with the roms in the *roms* folder.
Usage example (Windows):
```
emu-chip-8.exe roms/BRIX
```
The emulator is in **pause** state on start.
Use **p** to pause/play.
Use **n** to step to next operation.
