Ripping 3DS models without Gateway

[TGE]

....Or get lucky and find yourself a CIA of the game you want to rip that has the rom de-encrypted.
Download the cia. Open the cia with a hex editor > search for (ctrl+f) "IVFC".
Then cut out the data located before the IVFC string and tada- you got yourself a 3ds rom.
Don't be fooled though! Not all CIA files have the rom decrypted, but a lot of them do.
