Dump Settings

As noted earlier, you need a dump of BOTW on your PC to use UKMM. (If perchance you are curious why, here's an explanation.) I'll break down how to set this correctly per platform.

Wii U

For Wii U, you have two supported dump options: unpacked MLC files (most common) or a .wua file (Cemu-specific format).

For information on .wua files, check the changelog for Cemu v1.27.0b or the ZArchive repo. The rest of this guide will focus on an unpacked dump.

Unpacked Dump

There are three folders to specify for an unpacked game dump.

  • Base Folder: This folder is the root of the plain, v1.0 BOTW assets which were included on the disk. If you are using Cemu, it will usually be in your MLC folder, with a path such as this (part of the title ID will be different for the EU or JP versions):
    mlc01/usr/title/00050000/101C9400/content

    You can verify the path is correct if it contains Pack/Dungeon001.pack.

  • Update Folder: The contains the BOTW v1.5.0 update data. It is absolutely necessary for the game to even run. If you are using Cemu, it will usually have a similar path to the base folder, but with an E at the end of the first half of the title ID:
    mlc01/usr/title/0005000E/101C9400/content

    You can verify the path is correct if it contains over 7000 files in the Actor/Pack folder.

  • DLC Folder: This contains most of the assets for the BOTW DLC. This one does not usually end in content, but must go one level further into a 0010 folder because of the way multiple kinds of add-on content are handled. If you are using Cemu, it will usually have a similar path to the base folder, but with a C at the end of the first half of the title ID:
    mlc01/usr/title/0005000C/101C9400/content/0010

    You can verify the path is correct if it contains Pack/AocMainField.pack.

Switch

At present only unpacked RomFS dumps are supported, but in the future NSP or XCI support may be added. In the meantime, if you have an NSP or XCI, dump its RomFS using Yuzu, Ryujinx, or another tool.

Unpacked Dump

There are two folders to specify for an unpacked game dump.

  • Base Folder: On Switch, following the usual guides with nxdumptool, this will usually be the combined base game and v1.6.0 update files. The path will probably contain the title ID of 01007EF00011E800 and end in romfs.

    You can verify the path is correct if it contains over 7000 files in the Actor/Pack folder.

  • DLC Folder: This contains most of the assets for the BOTW DLC. The path will probably contain a title ID like 01007EF00011F001 and end in romfs.

    You can verify the path is correct if it contains Pack/AocMainField.pack.
