- Magnitude: 1.1 out of 10 — Quiet
- Stars: 3 total · +1 star measured 2026-10-20, 16:27–19:06 UTC, ≈ 1 by evening
- Star trust: star growth looks organic
- Category: Games & graphics · Language: C · Created: 2026-10-10 · Last push: 2026-10-19

## Useful for

- Build CIV.EXE from source with Microsoft C 5.1 and MASM in DOSBox-X
- Study the architecture and systems of the original Civilization via the technical book
- Verify the build matches the original executable against pinned hashes

## Why it’s here

- Star-counter measurements on 2026-10-20 (UTC), 16:27–19:06: 2 → 3 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +1 stars, using observed gains and the previous day.
- The repository is 10 days old and already has 3 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Hacker News: “Show HN: Civ 1 period accurate decompilation” — 9 points, 10 h ago.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 0
- Issues and pull requests: 0
- Watchers: 0
- Average over the last week: 0 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 0

## Stars per day, last 11 days (oldest → newest, today is partial)

2026-10-10 … 2026-10-20: 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
