A full online disassembler lets you specify the starting offset so that absolute memory addresses (like JP 1234h ) are calculated correctly. 3. Support for Undocumented Opcodes Accepts raw binary files or Intel Hex formats

Reverse engineering the Z80 is a rewarding way to peek under the hood of computing history. By using a , you bypass the technical barriers of environment setup and get straight to the logic of the code.

A performs the inverse operation of an assembler. While an assembler takes human-readable mnemonics (like LD A, 05h ) and turns them into machine code ( 3E 05 ), a disassembler takes those raw bytes and translates them back into mnemonics. A online disassembler isn’t just a simple table lookup
