Homebrew How to dump/datamine game data?

[Shaohs]

Hey, I'm trying to figure out how I can dump/data mine game data on the N3DS. Im running Luma + A9LH If that helps at all. Im trying to dump the data for Pokemon X/Y/OR/AS and Ace Attorney DD/SOJ
I really appreciate it if anyone can help

Braindump is the go-to app in this case.

Does a braindump CIA exist by any chance? When I attempt to use Braindump for homebrew, no games show up on the list except for homebrew itself

Okay, got braindump working by updatinv luma
Now I extracted the romfs folder. How could I find unused data within these files?

In a nutshell, compare what you find with what you know is used in-game. Some file types will be known, some unknown. For the ones that are known, search around places like this for tools you can use to extract data from those file types. For the other files, you'll have to use a hex-editor in some manner to figure out how to extract data from that type. I have no idea how to even start doing that, however.
