z88dk-dis disassembler for binaries/objects. Use to inspect codegen and library expansion.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Tool — dis

| | |
|--|--|
| Binary | `z88dk-dis` |
| Help | bare z88dk-dis usage |
| Wiki (local draft) | `wiki/tools/Tool-z88dk-dis.md` |

Prefer assembler `-l` listings for library sources. Use dis for linked binaries with map context when needed.

## Condensed reference (from wiki / tree)

# Tool — dis (`z88dk-dis`)

Multi-CPU disassembler. Load map/symbol files for named labels. Use with assembler listings when you need to see **expanded** synthetics in library sources.

## Help path

Bare invocation prints usage. Do not assume a uniform `-h`.

```text
z88dk-dis -mz80 program.bin
z88dk-dis -x program.map -o 0x8000 -s 0x8000 program.bin
z88dk-dis -m8085 program.bin
```

Put **`-x` map/symbol** before `-o` / `-s` / `-e` when symbols should apply to those addresses.

## CPU flags

Use the **`-m…`** form (same family as ticks/zcc): `-m8080`, `-m8085`, `-mgbz80`, `-mz80`, `-mz80n`, `-mz180`, Rabbit, kc160, ez80 modes, …

## Methodology

| Goal | Approach |
|------|----------|
| See what linked at an address | `-x prog.map` + start address from the map |
| Check 8085 vs Z80 opcodes | Match `-m` to the binary |

How to install

The exact contents, by fingerprint
mdr add feilipu/8085-skills/tool-dis@sha256:6e3b89513e5fbc54

The line at the top of this page pins the label git:20260821.71d8484, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
