3DS IconDecrypter

Template:Infobox-3DS-Homebrews It is now possible to dump 3DS Game Icons (those icons that show on the home menu) directly from your 3DS.

The process is detailed here: http://gbatemp.net/threads/3ds-game-icons.354707/

Basic Operations:

1/ Setting up XOR pads for decrypting other icon data:

3DS_IconDecrypter

• --genxor
• --iconcache="path to icon cache"
• --unused_slots=X
• --num_decrypt=Y
• --decdata="path to dir with plaintext icons"
• --xorpaddir="path to dir for output XOR pads"

• "X" = The number of icons that exist in the cache before the first icon you want to generate an XOR pad for.
• "Y" = The number of icons you want to generate an XOR pad for.

2/ Decrypting Icons from cache

3DS_IconDecrypter

• --decrypt
• --iconcache="path to icon cache"
• --unused_slots=X
• --num_decrypt=Y
• --xorpaddir="directory with XOR pads"
• --decdata="directory for outputing decrypted icons"

• "X" = The number of icons that exist in the cache before the first icon you want to decrypt.
• "Y" = The number of icons you want to decrypt.

Change log (v0.2):

• Command line arguments are now more flexible
• Performs basic checks on decrypted icon data to determine if decryption was successful
• Now comes with executables for Windows/Mac OS X/Linux
• Source code now available
