What this artifact is
High Low v1.0 is a Commodore 64 BASIC number-guessing game preserved from its author-controlled release. The program asks the player for guesses and responds with guidance until the hidden value is found. Its catalog record binds the hosted PRG to the published v1.0 source revision and retained Apache License 2.0 text.
This is an exact artifact record rather than a claim that C64 Vault created the game. The public source snapshot, upstream release reference, byte count, and SHA-256 digest identify the specific version being served. The component review covers the program bytes and license notice at that revision; it does not make a blanket rights statement about similarly named games, later forks, unrelated screenshots, or files obtained elsewhere.
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 High Low v1.0, the source owner is recorded as Keith Ott / ducttape12; the immutable source revision is 9d7a49154f9d38ea627b591694ee080baf14e5ac. The retained license is Apache-2.0. 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
Open the item in the workbench, wait for the browser-side digest check to pass, then start the local runtime. Use the emulated C64 keyboard to enter the guesses requested on screen. C64 Vault does not submit scores or game data to a server. Device media, this hosted item, and browser save-state behavior remain separate layers so that a successful launch cannot be misrepresented as proof about an unrelated file.
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.
