Z80 Disassembler

Modifying original arcade or home computer games to fix bugs, add features, translate languages, or introduce custom cheat codes.

Instruction lengths can vary from (e.g., NOP ) to 4 bytes (e.g., specific indexed addressing modes). Furthermore, the Z80 is a superset of the Intel 8080, meaning it retains the 8080 instruction set while adding a complex set of extended operations. z80 disassembler

This mimics the CPU's actual execution path and naturally avoids decoding data bytes, because they are never fetched as opcodes. Modifying original arcade or home computer games to

“To disassemble is to understand; to understand is to preserve.” NOP ) to 4 bytes (e.g.

For recursive descent, you must parse the operand to determine the target address.

Two fundamental approaches exist:
