SD Filesystem

Quincy: Verified both Excitebike EUR and Pokedex EUR

The 3DS uses an SD Card for general storage of additional game data, music and photos taken with the 3DS.

/DCIM - Photos and images downloaded with the Internet Browser
/Music - Music Files
/Nintendo 3DS - Game Data

Additional game data is stored here:

/Nintendo 3DS/<SomeID>/<SomeID>/extdata/00000000

0000008f - Some [[2.0.0-2]] data, unknown doesn't appear in extdata management.
00000207 - Mii Maker - JPN
0000020d - Face Raiders - JPN
00000210 - Some [[2.0.0-2]] data, unknown doesn't appear in extdata management.
00000217 - Mii Maker - USA
00000219 - eShop USA
0000021d - Face Raiders - USA
00000227 - Mii Maker - EUR
0000022d - Face Raiders - EUR
0000030c - Nintendogs + Cats - EUR
0000032d - Super Street Fighter IV 3D - USA
0000033b - Ridge Racer 3D - EUR
0000033c - Super Street Fighter IV 3D - EUR
0000034d - Samurai Warriors Chronicles - USA
00000358 - Ridge Racer 3D - USA

All "extra data" under [[extdata]] is encrypted. Although these files use 0xFF blocks similar to FLASH [[Savegames|saves]], extdata can't be decrypted with the xorpad fail like FLASH saves. All "extra data" files can't be copied to other 3DS SD cards, they are locked to the console.

With the introduction of the June update the folder structure changed slightly. You will now find "dbs" and "title" folders located in /Nintendo 3DS/<SomeID>/<SomeID>/ along with the extdata folder. "dbs" contains two files, import.db and title.db - usage currently unknown.

/title/00040000/ appears to contain eshop downloads (can someone verify these and add for different regions?):
00054e00 - 3D Classics Excitebike - EUR (verified)
00054300 - 3D Classics Excitebike - USA
00032600 - Pokedex 3D - EUR (verified)

"Private" data is stored here:

/Nintendo 3DS/Private/<Title ID Low>/

00020400 - Nintendo 3DS Camera
00020500 - Nintendo 3DS Sound

"Private" data for 3DS Sound/Camera are cleartext.
Under the camera priv dir is [[phtcache.bin]], this seems to list the pictures on SD card?
Under the sound priv dir is: voice/XX/*.m4a. Where XX is 01-10, with sound saved as .m4a.

Quincy:

How 3DS system judge encryption type? [[User_talk:Matyapiro|Matyapiro]]

Sorry the question is not understood. What do you mean? [[User:Neimod|Neimod]]

I think that he means "How does the 3DS decide what encryption method must be used" --[[User:Quincy|Quincy]] 23:47, 29 May 2011 (CEST)

===3DSを実際にハックしてみよう!===

この3dsbrewは3DSをハックするためのページです。

と言っても誰もその具体的な方法を言ってくれませんよ。もちろん。

ですが、それはハッカーとしてのプライドや、理解してもらう難しさにあります。

閑話休題。

単刀直入にいうと、セーブデータ（ポケモンでのレポートのこと）の内容を書き換える。

ということ。じゃあどうやってというのは後に回して、実際どうしてそんなことをするのか？という話。

ハッカーといえば、パソコンの前でキーボードをガチャガチャとたたいて、なんやら変な物を相手のコンピューターに入れて、...

というイメージがあると思う。でも、それは違う。（それはクラッカーだ。）我々はそんな連中とは違い、

「自分でプログラムを作る」者たちだ。そこから安全性を指摘するのが仕事でもある。

そのために、自分のもの(3DS)で自分のソフトやゲームを作りたい。と思うわけ。それができないのは、なんとなくかゆいところに手の届かない

歯がゆさと似ているんだ。そこで既存のゲームの書き換えられる部分、つまりセーブデータの中に自分のソフトを書き込み、

あばよくば動かしてやろうというわけ。

ではその基本的な流れを。

'''1''':ゲームソフトを起動し、セーブデータを読み込む

'''2''':セーブデータ内のデータを読み込ませ、実行する

'''3''':そこからさらにSDカード内のプログラムを実行させる

'''4''':3DSのメニューから起動できるようインストールする

というコンセプトになっております。

わかりましたか？

では、'''1'''は誰でもできますから、

次は'''2'''の詳しい方法からです。
