SimpleNES
SimpleNES es una aplicación de C++ que simula el hardware original de Nintendo Entertainment System para ejecutar juegos heredados en computadoras modernas. Funciona como un simulador de hardware y emulador de juegos retro diseñado para ejecutar ROMs de juegos clásicos recreando el entorno de la consola original a través de software.
El sistema implementa una versión de software de la CPU 6502 y la unidad de procesamiento de imágenes para renderizar video y audio de juegos retro. Recrea la arquitectura de consola de 8 bits para garantizar la ejecución de ROMs de juegos originales.
El proyecto cubre la simulación de hardware de bajo nivel, incluyendo emulación de CPU precisa por ciclo, entrada/salida mapeada en memoria y renderizado de píxeles con búfer. También incluye síntesis de audio basada en muestras para renderizado de audio heredado y un sistema de configuración para mapear teclas físicas del teclado a botones de controlador de juego emulados.
