ROM Hack [Tutorial] Change the UniqueID without Makerom/RSF

[Asia81]

Decrypt and Extract your game using my tutorial here.

Open your DecryptedExHeader.bin in HxD, and do a hexadecimal search with the UniqueID, reversed.
So if your UniqueID is 17 BA, search for BA 17 (It's Bravely Second USA).

Replace it anywhere it appear with the one you want.
Do the exact same thing with all HeaderNCCH.bin files.

It does not work with Pokémon Games [XY|ORAS|SM] due to the plainrgn.bin file.

Very useful without Makerom, RSF, and other things.

Thanks @xXDungeon_CrawlerXx for the help!

Very Handy! Wish I would have seen this before I started Music Hax For Pokemon Alpha Sapphire!

Finally I'll be able to install all SDK DevKit Tools, including the ones that already were in CIA

It's okay, changing Unique ID for Pokémon makes it crash anyway.

I extracted 3DS game Ever Oasis and the folder ExtractedRomFS/data/ contains only .gar files.
How to view them?
