- Debugging
- It provides step-by-step CPU tracing, state inspection, and SID change logging.checked 11 Oct 2026
- Disassembler
- Its assembly tools decode 6502/6510 instructions into readable mnemonics and metadata, and can disassemble memory ranges.checked 11 Oct 2026
- Disassembly
- Its Asm component decodes 6502/6510 instructions into mnemonics and metadata and supports disassembly.checked 5 Oct 2026
- Integration
