NES Emulator in C

This is a project for a NES emulator written in pure C. The main goal of this project is to emulate a Nintendo Entertainment System (NES) to run most of the classic games. This repo tries to port the original NES Emulator written by OneLoneCoder (javidx9) written in C++ into a pure C Emulator. Check the Acknowledgments section.
