zig64-v0.4.0

Release 0.4.0 - Major SID Decoding & Tracing Update

This release marks a major leap forward, focusing on advanced SID register decoding and tracing capabilities, elevating the emulator to a powerful tool for C64 software analysis and SID player routine dissection. With a stable core and no alpha designation, it’s ready for serious use while paving the way for future enhancements.

What’s New

• Advanced SID Register Tracking: Added cycle-accurate tracing of SID register writes with detailed change decoding (e.g., waveforms, envelopes), perfect for analyzing .sid player routines.
• Enhanced Debugging Tools: Introduced callSidTrace() and appendSidChanges() for comprehensive SID state analysis, alongside richer CPU step-by-step tracing.
• Documentation Polish: Updated README with new features, API examples, and component interactions.

Get ready to dive deep into C64 code and SID behavior—happy tracing, emulating, and experimenting!

zig64-v0.3.0-alpha

zig64 v0.3.0

This release enhances the zig64 Commodore 64 MOS 6510 emulator core with advanced instruction decoding and disassembly capabilities, a modular code refactor, and comprehensive documentation. Key updates include:

• Instruction Metadata Decoding: Added decodeInstruction() to decode 6510 opcodes into detailed Instruction structs, including addressing modes and operand metadata.
• Disassembly Functions: Introduced disassembleForward(), disassembleInstruction(), and disassembleCodeLine() for converting raw bytes into formatted assembly output.
• Code Refactor: Reorganized into modular files: cpu.zig, mem.zig, vic.zig, sid.zig, and asm.zig for improved maintainability.
• Updated Documentation: Revised README with a system overview, detailed API reference, and example code.

Happy emulating!
