Motion Transfer

Motion Transfer recovers a move from a compiled game, or from just a clip of it, and carries it into games the model has never seen. Getting a specific feel into your game usually means rebuilding it by hand and hoping, and it's harder still if the source is gone. It's for developers who want that feel in their own games, and for preservation teams working with games they have the rights to use. Muse Wonder rebuilt a dash from a 47 KB binary with no source code, and an exhaustive verifier showed all 4 accepted controllers match it on all 17,600 reachable transitions in the default configuration. Muse Spark then ported the dash into 7 of 8 eligible unseen games for an estimated $0.33, with every patch tested in an isolated worker. From footage alone, SAM 3.1 and Muse Spark Open scored 40/40 in 4 of 6 final sessions, and the other 2 were refused. The same kind of check also covers a drone's compiled arming logic, about 1.6 million transitions, though no model has recovered that one yet.
