Phase 2: Advanced Assembly Techniques

Build on your foundational knowledge to become a sophisticated assembly programmer. Phase 2 introduces advanced programming patterns, interrupt handling, complex data structures, and optimization techniques that separate professional developers from hobbyists.

What Makes This Different

Phase 2 moves beyond simple linear programs to sophisticated software architecture. You’ll learn to handle multiple concurrent tasks through interrupts, manage complex data relationships, and optimize code for both speed and memory efficiency.

This phase emphasizes practical techniques used by professional game developers and system programmers of the 1980s. Every concept is demonstrated through hands-on projects that build real-world programming skills.

Advanced Programming Concepts

Interrupt Programming - Learn to create responsive programs that handle multiple tasks simultaneously. Learn IRQ and NMI interrupts to build real-time applications that feel smooth and professional.

Complex Data Structures - Implement linked lists, trees, and hash tables in assembly. Learn to manage dynamic memory allocation and create efficient data processing algorithms.

Performance Optimization - Learn cycle counting, memory access optimization, and algorithmic improvements. Learn to profile code and identify bottlenecks just like professional developers.

Advanced Addressing - Use sophisticated addressing modes and indirect operations to create flexible, maintainable code that can handle complex data relationships.

Project Focus

Phase 2 centers around creating Mega Maze - an advanced puzzle game featuring smooth scrolling, real-time effects, and sophisticated AI. This project demonstrates professional-level programming techniques while creating an engaging, polished game experience.

Skills You’ll Develop

By completing Phase 2, you’ll have the same advanced assembly programming skills used by professional developers working on commercial C64 software. These techniques transfer directly to modern embedded programming, game engine development, and any field requiring high-performance code.
