Reporting from 1 source: Game Spark.
Bethesda Game Studios released a Fallout 4 update on August 18 local time, raising the BA2 archive limit from 256 to 1024 to support large mod collections. The patch adds Creation Kit fixes, PlayStation archive support, new file formats for Creations, and resolves crashes on Steam Deck and Microsoft Store.
Bethesda Game Studios shipped the previously announced Fallout 4 update on August 18 local time, and the headline change is a jump in the BA2 archive limit from 256 to 1024. That means modders can pack more assets into a single archive, which supports bigger and more complex mod environments without hitting the old ceiling.
The Creation Kit also gets a PlayStation-specific boost: archives are now supported on that platform, and new file formats (.nif, .dds, .bink, .cdx, .csg, .wav, and .fuz) can be used in Creations for PlayStation. Xbox uploads can now go up to 2GB. The patch also fixes crashes, including one tied to streaming audio errors and another on the Microsoft Store version when re-entering the Creations menu after an internet reconnect.
Fallout 4 is available on PS5/PS4, Xbox Series X|S/Xbox One, Nintendo Switch 2, and Windows. A Skyrim update is still in progress, with no release timing announced.
