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: [ Register or Signin to view external links. ]

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.
