A disassembler is a program that takes machine code (binary) as input and translates it into assembly language. This process is also known as reverse compilation or decompilation. The goal of a disassembler is to recreate the original assembly code from the binary data, making it easier to understand and analyze.

function getMemoryAddress(binaryData, index) { // ... implement memory address retrieval ... } operands

for (let i = 0; i < operandCount; i++) { const operandType = instruction.operandTypes[i]; let operandValue;

document.getElementById('disassemble-btn').addEventListener('click', () => { const binaryData = document.getElementById('input-binary').value.split(' ').map(byte => parseInt(byte, 16)); const disassembly = disassemble(binaryData); document.getElementById('output-disassembly').innerText = disassembly; }); This implementation provides a basic disassembler that can handle Z80 instructions with operands. However, it's incomplete and requires additional work to support all 252 instructions, operand types, and edge cases. This process is also known as reverse compilation

switch (operandType) { case 'register': operandValue = getRegisterValue(binaryData, pc + 1); pc += 1; break; case 'memory_address': operandValue = getMemoryAddress(binaryData, pc + 1); pc += 2; break; case 'immediate': operandValue = binaryData[pc + 1]; pc += 1; break; default: throw new Error(`Unsupported operand type: ${operandType}`); }
