Installation

Requirements:

  • A 3DS capable of generating XORPADS for legit 3DS to CIA.
  • Python 2.7.
  • Add Path to Windows Enviroments (e.g. c:\windows\system32;c:\python27).

Included in Package are:

  • RomFS Builder - Thx @ SciresM.
  • ExInjector - Thx @ piratesephiroth.
  • 3DSExplorer.
  • Notepad++.
  • ctrKeyGen.
  • Launcher.dat.
  • slot0x25KeyX (you need to insert the key, google it).

User guide

From .3ds to cia:

  • Create your xorpads and put all files into 3ds to cia dir next to Make batch.
  • Drag n drop .3ds/.3dz on Make batch.
  • Choose your Options and start.

Decrypt selfmade cia (no legit cia):

  • Drag and drop your cia on Make batch.

Extract decrypted .3ds (no legit/rebuilded/regenerated 3ds):

  • Rename your .3ds to <filename_modified.3ds>.
  • Drag and drop your .3ds on Make batch.

Quick rebuild from files inside folder:

  • Make sure all files are in the same Folder (romfs.bin/banner.bin/code.bin/exheader.bin/icon.bin/logo.bin/.rsf***).
  • Edit your .rsf to work as .3ds, not .cia.
  • Drag and drop your Folder on Make batch.
  • (***As for rebuilding .3ds, a working file depends on your Skill to modify your .rsf.)

Mostly there is not much to change, make sure to change at least:

  • Title / CompanyCode / ProductCode / UniqueId / MediaSize.
  • MediaType / CardDevice / ExtSaveDataId / SaveDataSize.
  • And if needed: JumpId.

You can take the sample-rsf-reb.txt and fill in the needed Details, from exheader.txt / info.txt and "rom_tool -i <gamename.3ds>".

You will see green texts when everything is running smoothly, if something went wrong the texts will be displayed in red.
