Homebrew Any way to decompress / extract content from 3DSX ROMs?

[XorTroll]

Hi again!
After a time researching I've achieved to do lots of successful conversions:
- CIA to 3DS
- 3DS to CIA
- 3DSX to CIA
- Using conversions above: 3DSX to 3DS (3DSX to CIA to 3DS)

All the conversions above are done using tools like ctrtool, 3dstool and makerom, and extracting CXI and CFA partitions if necessary.

But, for the moment, I have no idea how to do: 3DSX -> something (I don't even know if it's possible though)
Any way ro do this? If it's not possible, could you briefly explain the reason? (I just have curiosity)
Thanks in advance for any answers.
