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.
