ROM Hack How to extract content from CIA DLC with Japanese characters in filename?

[DeathChaos]

So I'm trying to extract my Fire Emblem: If DLC, I followed this tutorial and everything worked out nicely, however, I have run into a major problem that won't allow me to rebuild my DLC.

Instead of getting the correct filenames, the extractor is instead replacing all Japanese characters with pound signs, making it impossible to rebuild the romfs and thus the cia.

For example, in this picture, there should be 6 files, 2 of them should contain the name クロム "Kuromu", or Chrom, another 2 should be リズ, "Rizu" or, Lissa, and the final 2 "フレデリク", Frederick.

While renaming these particular files would be fine, there are still many more whose filenames I have no knowledge of, so some help in this would be greatly appreciated.

Hum try to run the rom builder in japanese language 日本語 using AppLocale. If you can't use it, change your system region to japanese.

RFSE, if you have the decrypted RomFS.bin available.

What is "RFSE" exactly ?

I was referring to the command used in Asia81's PackHack to open another RomFS extractor. I think it's just called "RomFS Extractor". Can't remember right now.

Oh okay !

That one works perfectly when extracting content from the Fire Emblem game's romfs, but Asia81's PackHack is not giving me a romfs file, otherwise I would've just ran it through that.

The problem itself is Ctrtools, which does not support Japanese characters, and the hack pack does not give me a romfs that I can run through RomFS Extractor.

Try to use another dumper, like 3dstools or this https://gbatemp.net/threads/release-ceed-mini-a-romfs-and-code-dumper-for-hans.402196/

Haven't tried 3dstools, but CEED doesn't seem to like DLC.

You should use RomFS Extractor (by SciresM) for DecryptedRomFS.bin

I know that, I've already extracted romfs for both Awakening and If, the problem is that the Pack Hack gives no DecryptedRomFS file for the DLC, it simply extracts everything in the romfs with ctrtools, and ctrtools doesn't support Japanese file characters.

I think you should decrypt the DLC pack manually. For example ("Before Awakening" DLC)

ctrtool -p --content=c decryptedDLC.cia
ctrtool -p --romfs=romfs.bin c.000e.00000029

Then extract all files in romfs.bin using RomFS Extractor.

Edit: If it doesn't work, try decrypting it in a traditional way (xorpads)

ctrtool -p --content=c encryptedDLC.cia
python ncchinfo_gen.py c.000e.00000029

Alright, I'll give this a try

Strange, used ctrtools to extract the contents from the cia, then tried to extract the contents from "Before Awakening", ctrtools gives me a romfs.bin, but RomFSExtractor says it's not a valid romfs binary, and I'm 100% sure I ran the DLC through Decrypt9, otherwise pack hack wouldn't have extracted it, I'm probably missing something very obvious here.

Did anyone solve this? I'm having the exact same issue trying to patch Fire Emblem Fates CIAs. The program is replacing Japanese characters with hashtags.

RomFS Extractor
repack with RomFS builder

thanks. It seems to be working. Just realized a hitch though. I seem to have neglected to download one of my dlc. I should be good though.
