Tested, not hyped
Procedures are reproduced on hardware we run before they are published. If we can’t verify it, we say so.
Dated and re-verified
Every guide shows when it was last verified. When firmware or a patch changes behavior, the guide is revised and re-dated.
Independent
Not affiliated with Cronus or any publisher. The site sells nothing — it documents.
Game hubs
Per-game mini-wikis: setup, patch impacts, and honest capability notes.
