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. z80 disassembler online full
const operands = []; let operandCount = instruction.operands;
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. 10 01 02 03 04 05 Click the
disassembly.push(` ${instruction.mnemonic} ${operands.join(', ')}`); pc += instruction.bytes; }
Here's a basic online Z80 disassembler implementation using JavaScript and HTML: const operands = []; let operandCount = instruction
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}`); }
const z80Instructions = [ // ... 252 Z80 instructions ... ];
function disassemble(binaryData) { const disassembly = []; let pc = 0;
if (!instruction) { disassembly.push(` Unknown opcode ${opcode} at PC=${pc}`); pc++; continue; }
