WyvrnChroma

A small, standalone .NET library to read and play Razer ChromaAnimation (.chroma) effects and the Wyvrn haptic-folder catalog that event-driven games (e.g. 007: First Light) use for their per-event RGB lighting — without Synapse, without the Razer Chroma services, and without any cloud dependency at runtime.

It exists so Aurora (issue #292) can react to SetEventName games on non-Razer hardware: Aurora reads the live event stream, looks up the event in the local wyvrn.config, and plays the matching .chroma itself.

What it does

.chroma parser (ChromaAnimation): decodes the ChromaAnimation file format into frames of per-LED colours. Pure managed code, no Razer DLLs.
animation player (ChromaPlayer): samples the current frame at time t (loop vs one-shot).
catalog acquisition (HapticCatalogProvider): local Synapse/Chroma/Wyvrn install first, else Razer's public CDN (manifest → sha256-verified ZIP), cached offline.
wyvrn.config mapping (WyvrnConfig): event id → per-device .chroma effect (+ loop/priority semantics).
public API (HapticCatalog / HapticGame): GetEffectForEvent(game, event, device) → the parsed animation ready to play.

Status

Phase A (this library) complete: parser, player, catalog acquisition, wyvrn.config, public API — all tested.
Phase B (the Aurora integration that consumes this library) lives in the wyvrn-chroma-292 branch of the Aurora fork, tracking Aurora issue #292.

Build & test

dotnet build -c Release
dotnet test  -c Release

Targets net10.0 (matches the Aurora consumer; cross-platform — no Windows APIs).

Notes

This library only parses/plays data files; it does not bundle or redistribute any Razer content. The catalog of .chroma/wyvrn.config files is Razer/Wyvrn content, obtained at the user's machine either from an existing local install or from Razer's own public CDN.
