The Ultimate Guide to Z80 Disassembler Online Full: Unlocking the Secrets of Z80 Assembly Language

Z80 Disassembler Requirements

1. The Heuristic Scan: The tool looks for the entry point. It identifies where the code begins. It sees the instruction C3 00 01 (Jump to address $0100) and follows the rabbit hole.
2. Subroutine Detection: It identifies a call instruction CD 45 20. It understands that this block of code is a function—a reusable routine. It likely labels this automatically as SUB_2045.
3. Data vs. Code Separation: This is the "full" feature. The Z80 mixes code and data in the same memory space. A primitive disassembler might try to read a sprite graphic (a picture of an alien) as if it were a command. It would output nonsense: XOR B followed by RST 18H. A full disassembler recognizes that the code jumps over this section and flags it as "Data Block," leaving the sprite graphics intact as .DB (Define Byte) directives.
