Hacking Is there a way to fully decrypt(unpack) DSiWare?

[Archexe]

I apologize, I would have posted this in the Ask! section, but nobody responds there from what I can tell.
I want to unpack a DSiWare that has a demo that can be sent to a DS via download play. Since it runs in DS mode, I could run it on my Wii U through VC injection and on flashcarts/PC emulators. The demo is the full game without saving, and it runs in DS mode like I stated before.

I assume DSLazy wouldn't work because of the DSiWare specific header.

Thanks!
