This page describes the formats/structure of the data stored in RomFS for [[Home Menu]] DLC, for themes.

=Control Content=
The control content has content-index 0. It's unknown what if any of this is Home Menu specific.

RomFS structure:
* "MetaDataContentHeader.bin": Unknown, size is 0x44-bytes.
* "ContentInfoArchive_<region>_<lang>.bin" Contains the list of ''all'' DLC content available under this DLC title(which can include DLC that's not yet accessible via the shop). <region> can be "USA", etc. <lang>, for the US title: "en", "es", "fr", and "pt".
* "icons/<decimal_id>.icn" Contains the raw DLC icon image data, without any header. 48x48 tiled RGB565.

ContentInfoArchive entry format, size 0xC8(this file contains the following entry for each of the DLC content):

The first entry is a "header": contentindex val=1, second word = <total DLC content excluding DLC control content>. The two strings are set to dummy text.

=Theme Content=
RomFS structure:
* "bgm.bcstm": Background music, see [[CSTRM|here]].
* "body_LZ.bin": LZ11 compressed blob containing the rest of the theme data(graphics + optional [[BCWAV|CWAVs]]).

The filesize is aligned to 0x10-bytes. The filesize must be at least 0xC4-bytes, due to padding/alignment the first block of data after the header is normally located at 0xD0.

With the solid-color data, there's 5-bytes located at the solid-color data offset. With draw-type val2, there's 7-bytes located here. The first 4-bytes located here is RGBA8888 pixel data, the rest is unknown.

With draw-type val2, texture5 is also used(this likely isn't used for the entire top-screen). With draw-type val2, an extra texture with the same format/dimensions as texture5 can be used, when the additional texture offset field is set.

The filesize is aligned to 0x10-bytes. The filesize must be at least 0xC4-bytes, due to padding/alignment the first block of data after the header is normally located at 0xD0.

With the solid-color data, there's 5-bytes located at the solid-color data offset. With draw-type val2, there's 7-bytes located here. The first 4-bytes located here is RGBA8888 pixel data, the rest is unknown.

With draw-type val2, texture5 is also used(this likely isn't used for the entire top-screen). With draw-type val2, an extra texture with the same format/dimensions as texture5 can be used, when the additional texture offset field is set.
