To deepen my understanding of classic computing systems and explore the intricacies of low-level programming, I embarked on creating a 6502 CPU Emulator. This project stems from my fascination with the Nintendo Entertainment System's architecture, but focuses on the foundational 6502 processor to ensure broader applicability. By meticulously implementing the CPU's 8-bit architecture with its 16-bit address bus, I've created a tool that not only emulates the processor's functionality but also serves as a learning platform for myself and others interested in retro computing. Through this emulator, I can now experiment with and visualize the inner workings of a processor that was pivotal in early personal computers and gaming consoles, without the need for physical hardware.

My 6502 CPU Emulator offers a comprehensive replication of the processor's core components, including its three general-purpose registers, stack pointer, program counter, and the crucial processor status register. I've implemented all 56 instructions across 13 addressing modes, ensuring accuracy in instruction execution. The emulator supports features like little-endian architecture and can address up to 64KB of memory, mirroring the original hardware capabilities. While currently focused on instruction-level emulation, I plan to incorporate cycle-accurate techniques in future iterations to further enhance its precision. This project not only serves as a technical achievement but also as a valuable educational tool, allowing users to gain hands-on experience with assembly programming and understand the fundamental principles of processor design that underpin modern computing.
