ROM Hack Fire Emblem IF 'Not a valid Romfs Binary'?

[Cilerba]

I noticed some other people were having trouble extracting a romfs directory from a decrypted romfs.bin due to the Japanese characters in the file system, but I never came across a fix for this. Any idea how to fix this?

Have you tried RomFS Extractor?

 

[Cilerba]

Yes and I received that error in my title.

A valid RomFS file should have "49 56 46 43" (IVFC) as its first four bytes. You probably did something wrong in the decryption process.

• If you use ctrtool, make sure that you use -p option in ctrtool.
• Generate xorpads again. Your xorpad might be bad.
• Only original, unmodified ROM need xorpads. If you are working with modified ROM, xorpads is not needed.
• Verify your ROMs. Here are some MD5:

  If you are using your own dump, remove the header first before checking its hash.
