What this artifact is
8 Bit Island is a Commodore BASIC text adventure published with source under the MIT License. The admitted PRG is tied to a pinned upstream commit and an archived source snapshot. The experience is driven by typed commands, making it both a playable work and a readable example of a source-available C64 program.
The item entered C64 Vault through the same evidence model as every other hosted artifact. The catalog records the source owner, immutable revision, license text, exact public path, byte count, digest, structural format result, malware-scan receipt, and browser-runtime observation. The record is narrow by design: it applies to these exact bytes and does not turn the site into a mirror of every file found in the repository or on other C64 websites.
Why it is admitted
C64 Vault admits an artifact only when the source, redistribution basis, integrity, runtime compatibility, publication quality, and withdrawal path can be bound to one exact record. For 8 Bit Island, the source owner is recorded as gpowerf; the immutable source revision is f3d91c3357084a892569808a384567a0cb2b1641. The retained license is MIT. The artifact scan and format check passed for the exact digest shown below.
Admission does not mean that every similarly named file is approved, and it is not a promise that all browser, hardware, or input combinations will behave identically. It means the evidence gates passed for this revision and these bytes. A later contradiction, rights challenge, hash mismatch, or runtime regression can move the record out of the public catalog through the documented withdrawal process.
How to use it
Choose 8 Bit Island in the Open Library, select Verify & open, and start the local runtime after the integrity check passes. Enter the commands requested by the adventure through the emulated keyboard. Because this is a text-led work, reading the program’s prompts is part of the original interaction. C64 Vault does not alter the admitted PRG to add tutorials, tracking, ads, or a network leaderboard.
