ROM Hack Problem to extract a RomFS from a CXI from Braindump with 3dstool.exe

[Asia81]

Hi, I dumped some cxi using Braindump.
But I can't extract the RomFS partition with 3dstool.exe
Anyway, I can extract it fine using ctrtool.exe, but not 3dstool.exe.

I noticed the RomFS is not the same between from a CXI (Braindump) and from the CIA. The size is also not the same.

Size:

Any ideas?
