You should take an aspirine and re-read your last messages, Brony.

Aggressive posts will just make people avoid you because of the toxicity you post publicly. You "Okay Frenchie" Bullshit have nothing to do on GBATemp forums.

Can you imagine being forced to answer as soon as you get a notification because you are online ? Maybe Asia81 was busy with something other / had other things to do ? He surely MUST be devoted and answer like a good little dog to every person posting in this thread, right ? He does not owe you anything, and if he can not or does not want to answer, it is not a reason to insult him.

I'm not sure on which side the selfish individual is.

Hey, I'm a little stuck on the decryption part. I have GodMode9 installed, so I was going to use that. When I navigated title it was a .app. I decrpted that, and got another file with a lot of 0's followed by a . then the title's ticket and finally the .app. I then tried to use Decrpty9 but it wont even start.

EDIT: I'm trying to decrypt a eshop game.

EDIT2: I figured it out. I had to use godmode9, select all the files and the folder, then build a CIA out of that. Then, if that is not decrypted, decrypt that.

@Asia81 Hello! I just got my Alpha Saphirre decrypted and extracted, and I was searching for some roms hacks and I found your Rom Hack Named GBAlpha Saphirre... Is there an alternative download link since your download has been taken down?

Hey, sorry for being a complete and utter noob at this, but how would you go about doing this for Citra? I want to play Pokemon Moon Randomized on my PC, but I can't seem to be able to rebuild my .3ds file. Anyone know why?
Wich option of dumping did you choose? For citra you have to choose Extract and Decrypt (Trim)

I noticed that she's online when I made my reply, but @Asia81 probably doesn't care enough to help people when they have problems with THEIR TOOL!!!
Selfish people these days.

Actually you have to keep your extracted folder safe
No need to copy and paste
and when you rebuild, put everything in the same folder

Not sure if this has been said, but Im pretty confused about what how to access the romfs folder. I am using a cia file named "Pokemon_Edited.cia" but when I attempt to load the file in 3ds explorer it just says "Error: Error opening ticket" and wont load any files in the cia. Can anyone help me with this?

Have you even followed the tutorial in the first post? You get the romfs folder by following it.

Hi, surely this is not the topic here, but here is my query actually on Pokémon trash your link for Pokémon Purple Purple does not work anymore so I try in vain to convert Rom to CIA but every time I run I have the black screen I would like you to explain to me the procedure to follow in order to convert it correctly.
Cordially

Ps: sorry if I do not post on the right topic but I have not found any other link that is most relevant to my request.

So, I have extracted my CIA file of Pokemon Sun, and edited all the things I needed to. Then I recreated my romFS folder and my exeFS folder. The problem is, I can't use HANS in order to load a romFS file for Pokemon Sun. So, I need an alternative of running a romFS file OR a way to rebuild these files back to CIA format. (Yes I did follow the first part guide)

I can't work anymore on it until I bought a new computer.
Anyways you can extract the cia, but can't rebuild it?
PS : HANS is dead and deprecated (not sure if it's the good term) you should use LayeredFS instead (using NTR or Luma3DS).

Are there any known issues with Fire Emblem Fates? I extracted the .3ds without any obvious problems but when I rebuilt it after changing a couple of files, it was missing 1.3gb of file size (the rebuilt .3ds was ~515mb, the original was 1.8gb). I just rebuilt it again using a clean extract and it's 76kb.

is it my correct assumption I can with this tool.

1. dump game from Cart with godmode9 (decrypted 3ds)
2. dump game update to cxi
3. unpack .3ds with this tool
4. unpack .cxi with this tool, overwriting with updated files?
5. repack with this tool to make an updated .3ds?

for some reason the resulting .3ds is only 1/4 the original size...

edit: okay it was smaller cause I ran out of space, fixed now 20+ free.
I tried again and now it worked :D
