Z80 Disassembler Online Full
In this post, we've explored the concept of a Z80 disassembler and provided a basic online implementation. While this implementation is incomplete, it demonstrates the fundamental steps involved in creating a disassembler. If you're interested in working with Z80 code or reverse-engineering old microcomputers, a Z80 disassembler is an essential tool to have in your toolkit.

To use the online disassembler, simply copy and paste the following binary data into the input field: z80 disassembler online full
for (let i = 0; i < operandCount; i++) { const operandType = instruction.operandTypes[i]; let operandValue;
if (!instruction) { disassembly.push(` Unknown opcode ${opcode} at PC=${pc}`); pc++; continue; } In this post, we've explored the concept of
10 01 02 03 04 05 Click the "Disassemble" button, and the disassembler will output the corresponding Z80 assembly code:
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. implement register value retrieval
function getRegisterValue(binaryData, index) { // ... implement register value retrieval ... }
