The files inside this directory are not listed in the game's resource size table.

The Local directory appears to be a development remnant. It is unused in release versions and is not present at all on Switch.

Content/Local

System/RegionLangMask.txt

Identical to the regular Content/System/RegionLangMask.txt on Wii U. Unused in release versions.

Actor/ActorInfo.product.byml

Analysis of the executable reveals that during development, ActorInfo.product.byml was loaded from Local/ActorInfo.product.byml.

In release versions, the game will still load from Local if a debug heap is present in the init parameters (sead::Heap* at offset 0x8) or if a flag is set in the GameConfig structure (bool at offset 0x3d0)[1].
