The Zilog Z80, introduced in 1976, is one of the most influential microprocessors in history. It powered everything from the Game Boy (custom LR35902, a Z80 derivative) and the Sega Master System to the Sinclair ZX Spectrum, Amstrad CPC, MSX, and countless arcade machines. Even today, it thrives in embedded systems, retrocomputing, and hobbyist scenes.
Small, pure-code binaries or as a fallback within a hybrid analyzer.
This is where the challenge peaks: changing an instruction's length (e.g., JR to JP ) breaks absolute addresses. You need a or a binary rewriter . z80 disassembler

Z80 instructions vary from one to four bytes in length. If a disassembler starts parsing from an incorrect byte offset, the entire downstream assembly output will experience an instruction alignment shift, invalidating the output. 3.
