Key Responsibilities
- Studying NES hardware architecture
- Implementing 6502 CPU in C++
- Building memory bus system
- Planning PPU and APU components
Project Insights
Learning hardware architecture, CPU instruction sets, memory mapping, and emulation techniques from first principles
Technical Concepts
- 6502 CPU instruction set and register architecture
- Memory bus with address and data lines
- NES memory map with ROM, RAM, and I/O regions
- Clock cycle accuracy and timing
Architecture & Features
- CPU opcode decoding and execution
- Memory read/write through bus interface
- Addressing modes (immediate, zero page, absolute, indexed)
- Instruction pipelining and cycle counting
Key Learnings
- Emulation requires deep understanding of hardware architecture
- Cycle-accurate emulation is complex but necessary for authenticity
- Building from scratch teaches system design fundamentals
