## Description

This project is a Nintendo Entertainment System emulator written in Go. It functions as a hardware simulation that executes game ROMs by mimicking the original console's circuitry, including the processor and picture processing unit.

The emulator includes a game library browser that identifies local files and retrieves titles and thumbnails from online databases using file checksums. It also implements a system of memory management mappers to ensure compatibility across various game ROM formats and hardware configurations.

The software covers high-level capabilities for game ROM execution and retro game playback. It further provides input control translation to map keyboard or joystick presses to simulated hardware controller actions.
