What this artifact is
Laser Invaders is an open-source C64 arcade game provided as a complete D64 disk image. The admitted image comes from a pinned author-controlled repository revision, is retained under the MIT License, and is identified by an exact 174,848-byte size and SHA-256 digest.
A disk image carries more structure than a single PRG, so the catalog records both its recognized D64 size and its exact binary identity. The page does not infer authenticity from the file extension alone. The source snapshot, license evidence, scan receipt, runtime result, and immutable hash are separate proofs. If any one of those gates becomes invalid, the withdrawal process can remove the item without weakening the policy applied to the rest of the library.
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 Laser Invaders, the source owner is recorded as TedDallas; the immutable source revision is 860c6e95767d279e2335a26dbf79fb4c9e2d3f39. 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
Select Laser Invaders in the Open Library, verify the file, and start it in the browser workbench. Use Arrow keys or WASD for movement and Space for the mapped fire action once the program reaches its playable state. The workbench keeps the original disk-image bytes unchanged. Its keyboard mapping, theater mode, and fullscreen controls are interface features outside the artifact rather than edits to the game itself.
The isolated emulator surface remains advertising-free. This article is a separate information route. Google-controlled advertising may or may not be delivered here after consent and site approval; no advertisement is inserted inside or over the workbench.
