ROM Hack Possable to merge update into game CIA?

[Natsuru]

Can anyone point me to any info on how to integrate a eshop update into a game?
I would like to backup my Pokemon ORAS games and update 1.4 into a one stop cia install then do some modding later.

Any advice?

I've found taking the code.bin, ExHeader.bin from the Update and Merging the Update romfs with the base game is the way to go, also make sure makerom has the correct -ver set.

I don't believe online works when you do this though, could be wrong its been awhile since I tested but pretty sure when I first tried this out the game told me to update when I tried to connect online, maybe when connecting online it looks for the TitleID of the update or something along those lines?

By "taking the code.bin and exheader" do you mean removing them entirely, or adding them to the final cia with the update incorporated?

Basically I want to have Pokemon ORAS integrated with update 1.4 as a single CIA.
Ie New console > install 1 CIA > Game is installed with update 1.4.

I mean copying the code.bin and exheader.bin from the update cia and placing them over the versions in the base game cia.

Thank you. I was trying to merge Pokemon moon with the 1.1 update earlier, but it didn't work, probably because I didn't do that.

I extracted the game and update with HackingToolkit3DS I found the code.bin but can locate the exheader.bin.
I'm new to this, if there is a guide to follow I would like to give it a look over. Otherwise where is the exheader.bin normally located?

You can just copy the romfs of the update and just merge it into the romfs of your base game cia. You don't need the exheader.bin and code.bin as far as I know. That's just for the update to actually work with the game AFAIK.

Cool, Ill try it and get back to you.

Which installs a cia on to your system. Without the use of cias, you can't install anything or play anything unless you have a cart that can run .3ds files.

Use decrypt 9 to dump card to cia. It'll convert the game with the current update data into one cia. I just did this with pokemon moon.

Can you tell me what you selected in D9?

If the game makes any changes to the code you will need that and then the ExHeader is needed since that contains a reference to the size of the code.bin.

Some games you might get away with just the romfs but if an update has the code.bin you should be taking it.

I pressed dump card to cia. It then took about 10 minutes but it took the recent update and merged them together.

Oops yeah you're right, I forgot about that.
