Abstract Assassin’s Creed: Origins (ACO) relies on a proprietary engine architecture that references game assets via 64-bit hashed identifiers rather than literal file paths or string-based IDs. This paper explores the technical methodology behind "Inventory Editors"—third-party tools used to modify player save states—specifically focusing on the generation, management, and implementation of Hash Lists. We examine the transition from logical item names to FNV-1a 64-bit hashes, the challenges of collision resolution, and the reverse-engineering processes required to map the game's item database. 1. Introduction The development of third-party tools for single-player role-playing games often centers on the ability to manipulate save game data. In Assassin’s Creed: Origins , save files are serialized binary blobs that store player progress, world states, and inventory data. Unlike earlier iterations in the franchise which may have used integer IDs or strings, ACO utilizes the Dunia/Anvil engine's method of referencing entities through compiled code hashes. An Inventory Editor must therefore possess a comprehensive "Hash List"—a translation dictionary mapping human-readable item names (e.g., "Predator Bow") to their corresponding 64-bit hexadecimal hash values stored in the game memory. 2. The Hashing Architecture 2.1. The Identifier System In ACO, every item, weapon, mount, and outfit is an entity defined within the game's master data. To optimize memory lookup and prevent string processing overhead during runtime, the engine refers to these assets using 64-bit keys. 2.2. The FNV-1a Algorithm While the specific implementation details are proprietary to Ubisoft, the hashing algorithm most commonly associated with Dunia/Anvil engine assets is a variation of the Fowler–Noll–Vo (FNV) hash function, specifically FNV-1a (64-bit) .
