Z80 Disassembler Online Full _best_ Review
Learning low-level computer architecture and understanding how compilers optimize code for 8-bit registers.
(masswerk.at): A classic, clean, and highly reliable tool. It offers linear disassembly with a clear table output, supports Intel-hex and raw binary input, and allows users to set the origin address (starting PC). Its simplicity and correctness make it a first stop for many.
Save the generated text output as a .asm or .s file for editing in your local text editor. Common Assembly Mnemonics in the Output

As WebAssembly (WASM) matures, we are seeing full-featured disassemblers and even lightweight emulators ported to the browser. Projects like (experimental) and binjgb (Game Boy emulator in WASM) hint at a future where an online Z80 disassembler could offer recursive analysis, control-flow graphing, and even live debugging, all without installation. For now, however, the existing class of online Z80 disassemblers strikes an excellent balance between ease of use and practical utility. Its simplicity and correctness make it a first stop for many
Ready to start? Load your first ROM into a full Z80 disassembler today and unlock the secrets of 8-bit history.
Configure the entry point (e.g., 0000 or $4000 for ZX Spectrum ROM).
Imagine you are a digital archaeologist. You have found an old floppy disk containing a game you loved as a child, let's call it "Galactic Conqueror." You want to fix a bug, translate the text into English, or simply understand how the programmer squeezed so much action into 48 kilobytes of RAM. Share public link : A modern, interactive online
Does anyone know a better full online tool? Or a way to run z80dasm in a browser (WASM, JS port)?
Even today, developers, retro-gamers, and computer historians engage with this classic architecture, often needing to understand original machine code. This is where a tool becomes invaluable.
Tell the disassembler where the code starts in memory. For example, CP/M programs usually start at $0100 , while many ROMs start at $0000 .
