Read: second-top line of first post of PK3DS.

Please do not ask (nor private message me) how to obtain/dump/decrypt/unpack/repack ROMs as that is unrelated to the functionality of this program.

I've split off your post, since it's explicitly warned against in PK3DS thread first post.

You will need to search the net on how to extract files from the games. Best I can point you to is here, here and here.
(Don't ask me about how to use them, tho, as I won't be of much help in those categories. You gotta find that out yourself. Two of those links above are guides anyway..)

You could always google it.

"Bad IVFC Header"

RomFS - 3dbrew

> The RomFS is wrapped inside a IVFC hash-tree container, and the actual data is structured like a node-based tree

Since you're trying to extract the RomFS and the program is giving you an error saying something is bad, you should probably double check your ROM dump. It's probably a bad ROM dump.

Try another tool to extract to confirm.
