    Hi, I've dumped my eShop games using FunkyCIA and I would like to make them region free. I know that I have to change icon.bin and I can do this even using decrypted CIA, but after such change I need also to generate proper signature for that NCHH. How should I do that?

    I've had success with using Decrypt9's "Cia decryptor - full", decompressing with PackHack, editing, creating a .3ds with PackHack, and finishing with Simple 3DS to CIA 4.3 (iirc) -- a fakesigning sufficient to install and run under CFW is automatically handled, and of course you can't get a legit cia (for everyone or yourself) out of this!

    @Ryccardo thank you for the response! I am aware of this method but using 3dsbuilder included in PackHack you will lose manual for the original game which is my aim here - I want manual to also be included in generated 3ds/cia.

    @Ryccardo I have downloaded ctrtool, 3dstool and makerom - I've found some documentation on 3dbrew but I can't find good docs for ctrtool and 3dstool, and --help command is not really helpful since it doesn't even list every possible commands, e. g --content and possible set of parameters for it. I cannot make anything of it :(

    @EDIT

    @Ryccardo Thanks! I did it just as it was described in the link you've given to me! Below my input on keeping manual in the CIA:

    Code:
    makerom -f cia -o zelda-seasons2.cia -content game.0000.00000000:0:0x00 -content game.0001.00000001:1:0x01 -major 0 -minor 0
    
    game.0000.00000000:0:0x00 - cxi containg the game, banner, icon, etc
    game.0001.00000001:1:0x01 - extracted manual
