Games, plural
No single title, no rotation schedule. New releases, long-running saves, gacha pulls, horror I regret agreeing to, and the occasional bad idea played all the way through to the end.
If it looks interesting, it goes in the queue.

JOHNNYRUNTIME
Autoregressive narrative engine
A variety VTuber assembled out of one developer's leftover telemetry, running on a stream engine I wrote myself. Whatever game is worth playing that night, plus live C# work on the Kernel, the software that runs this whole channel. Chat is not a sidebar here. It is the prompt.
No StreamElements. No hosted overlays. Every alert, every token in the chat readout and every node on the Grid is drawn by software running on this desk.
What's on the stream
three threadsBuilding the Kernel
Live .NET 8 and C# work on the software that runs this channel. Overlays, Twitch EventSub plumbing, VNyan props, the lot.
Bugs get fixed on camera. Some of them twice.
The Grid
Chat is not a sidebar. Every person talking becomes a node with a fixed, hash-derived position, so regulars always light up in the same place.
Go quiet and your node fades. Come back and it holds again.
The machine already knows you
deterministicYour Twitch username hashes to one permanent designation. Not assigned, not stored, not looked up. Computed. The same name resolves to the same value on any machine, forever, including the first time you ever type in chat.
Nothing leaves this page. The hash runs in your browser, there is no account, and no request is sent anywhere.
Ask the Kernel directly. Type !checksum in chat and it will
resolve your designation live.

Props attach to real bones on the model with a time to live and oldest-first eviction, so the shelf never overflows. The scan drives an OBS filter, not a video file.
The Johnny Runtime Kernel
self-hostedOne rule: the Kernel decides, everything else renders. No logic in node graphs, no logic in the overlay, no logic in the plugin. If a behaviour cannot be tested, it does not live outside the Kernel.
- Runtime.NET 8 and ASP.NET, running locally on port 5178. No cloud dependency, no third-party overlay service.
- EventsTwitch EventSub over WebSocket: follows, raids, redemptions, ad breaks, and stream online and offline transitions.
- OverlaysBrowser sources drawn from scratch. Boot and dive sequence, chat with a BPE-style tokeniser, alert cards, the Grid, follower capacity.
- AudioEvery alert sound is generated at runtime with the Web Audio API. There are no sound files.
- AvatarVNyan bridge plugin for bone-attached props, TTL eviction and a hardware dead-man switch.
- SessionsEach stream is recorded as a numbered build with its own JSON record. Build 0000 was the first.
- StateViewer history, build counter and session records live outside the install folder, so a deploy is delete and paste.
Questions
answeredWho is Johnny Runtime?
Johnny Runtime is a variety VTuber and Twitch streamer, presented as an autoregressive narrative engine instantiated from the telemetry of a developer known only as Root. In practice that means games, live C# development, and a stream setup written from the ground up rather than assembled out of hosted widgets.
What games does Johnny Runtime stream?
Variety, so no fixed game. Whatever is worth playing that week: new releases, long-running saves, gacha, horror, and things picked purely because chat dared it. Development streams on the Johnny Runtime Kernel run alongside the games.
When does Johnny Runtime go live?
There is no fixed schedule at the moment. Follow on Twitch and you will get a notification the moment the stream starts, which fires as soon as the Kernel logs the go-live event. Every session is a numbered build, and the stream title updates itself when it comes online.
What is the Johnny Runtime Kernel?
A self-hosted .NET 8 service that runs the entire channel: Twitch EventSub handling, chat and alert overlays, avatar props through VNyan, OBS effects, session recording and the build counter. It runs on the same machine as the stream and talks to the overlays over WebSocket. Nothing about the channel depends on a third-party service staying online.
What is the Grid?
The Grid is the chat overlay. Every person who talks becomes a node whose position is derived from a hash of their username, so a returning regular always appears in the same spot. Nodes fade from green through amber over fifteen minutes of silence and brighten again when you speak. The overall brightness follows a stability score that decays on a ninety-second half-life.
What is a build number?
Each stream is a build, counted from zero. Build 0000 was the first session. The counter increments when the Kernel sees the stream come online, never resets, and appears in the stream title and in the session record written to disk afterwards.
What is a checksum designation?
A permanent name the machine derives for you rather than remembers. Your Twitch username is hashed with SHA-256 and mapped to an adjective, a noun and a digit, for example AMBER-STABLE-7. Because it is pure maths with no storage behind it, the value is identical on every machine and never changes. You can resolve yours above.
Is Johnny Runtime an AI?
Johnny is a character with a machine's premise, performed live. The Kernel behind him is real software and everything it does on screen is genuinely computed, but the person talking is a person.
