Hey Guys,

I wonder if it may be possible to extract/rebuild the .dat-files inside the romFS of Fire Emblem: Three Houses.

I'd like to extract/edit Ingame Models of that game, if possible.

QuickBMS + arslan.bms script will unpack files without correct filenames. It can't replace files in archives.
Tried it

Where can I find the IDX File for it?


EDIT:
Using the filecutter.bms gives me two 2048kb files

but renaming them to DATA.idx and use the arslan.bms doesn't work either. (DATA1.bin and DATA1.idx are in the same folder)

Mind explaining how to extract the bin files and sharing the bms files you use?

All text files have a header:
0x1 0x1 0x20 0x10

Starting at file 30776, begin the SARC archives.

File 70, 71, 72, 73, 74, 537 are font graphics.

Compressed archives have a structure:

uint32 size uncompressed chunk
uint32 chunk count
uint32 uncompressed file size

For I to chunk count
uint32 compressed chunk size with meta

chunk:
uint32 $size
[$size]: zlib data

Maybe someone else knows information.

Hmm, arcording to quickbms script SARC archives are between 65a3-65d6.

They contain some textures (bntx) like profile images of students, cursors, loading parts when game is booting, chapter background, etc + 2D layouts (bflyt) for them, animation data (bflan) + sometimes shaders (bnsh+bushvt).

Edit: Now I understand you are using custom tool from other topic. But in this case has some issues.

So for now we have
- SARC archives (contains BNTX textures, BFLYT layouts, BFLAN animations, BNSH+BUSHVT shaders) - can be opened with Switch Toolbox
- KTSR files (probably sound files)
- GT1 textures (they can containt many texture files and contains also mipmaps) - Can be opened with Switch Toolbox (some of them are crashing because of mipmap error)

Some files after decompressing with quickbms (f.e. 8e3) and linkdata tool are still compressed with zlib. After uncompressing they are not readable.

Pretty messed up thing. :D

I found only 1 .g1tg file (GT1G0600 magic). The rest are either inside the zlib archives, or I made a mistake in unpacking.

Edit: I write a tool that gets .ktss from .ktsl2stbin and converts to .wav using vgmstream.

So for the Updates, is it something we can extract as files, or is it diffs instead?

I'm really curious as to what they've added/changed.
