Visual effects: CPU particle simulation (emitters with constant, curve or random start values, rate, bursts and cycles, stepped or sampled at a time; modules, collisions and events), effect documents and Unity particle-system import, GPU particle dispatch plans, trails, ribbons, beams, and screen shake

AudioPort and the real-time AudioEngine: lock-free mixer, bus graph, effects, HRTF, streaming, granular voices, time-stretch and sfxr sound effects; WAV, Ogg Vorbis and Opus decoding, Ogg Opus encoding; device output through cpal and, in the browser, scheduled Web Audio buffers

2D vector graphics: paths, strokes, gradients, clips, view boxes, hit-testing, tessellation, CPU raster and SVG import

Icon model, SVG path grammar, and the bundled Lucide and Phosphor icon sets

Input mapping from host events to the title's own action enum: ActionSystem<A> with contexts, players, deadzones and tap/hold triggers, the per-step InputState, Actions<A>, rebinding, keyboard shortcuts with platform glyphs, virtual sticks, drag look, IME buffer, and gilrs or SDL2 gamepads

Game AI: blackboard, behavior trees, utility AI, hierarchical FSM, budgeted ECS scheduling, decision traces, GOAP, HTN, Monte Carlo tree search, perception, spatial queries, smart objects, influence maps and optional motion-matching training experiments

Asset server with typed handles, async imports, a content-addressed cache, hot reload, download packs and generated cells on a web worker; texture pipeline for PNG, JPEG and KTX2 with Basis Universal transcoding and encoding; glTF 2.0 importer

Runs models: the inference Port (InferPort) with on-device null, scripted, host-fed, cascade, dense MLP and tract ONNX backends and per-call limits, typed decision models on candle or ONNX Runtime, calibration, a text generation Port (GeneratePort) with a cost ledger and spend policy, read-only gateway request receipts and input verification, and an on-device speech-to-text Port (TranscribePort); remote HTTP clients use generate-http and SenseVoice uses transcribe-sensevoice

ZenGPU shader macro: compile GLSL or ZSL to SPIR-V at build time.

Convert emulator saves and memory cards to and from the Universal Saves Format (.1saves)

Procedural macros for Keel UI: #[component], #[derive(StableKey)] and the view templates behind col!, row!, stack! and children!, and the generated-content recipes image!, sfx!, music!, video! and character!

The 1saves command-line tool: convert emulator saves and memory cards to and from the Universal Saves Format

Networking Ports: HTTP, WebSocket, streams, nearby peers, online sessions, turn matches, relay allocation and Intent transport, with null, scripted and host-fed implementations and native ureq and tungstenite backends

The template grammar of Keel's view macros (col!, row!, stack!, children!) as a library: the macros expand through it and tools scan title source with it, so both compute the same templates, node indices and template ids

Identify a CD/DVD disc image: which system it is for, and the serial printed on the disc
