ROM Hack [Tutorial] How to Decrypt, Extract & Rebuild 3DS|CIA|CXI Files

KryptoBeastYT · Mar 7, 2021

My dbz game has spaces in between AND has a .3ds extension.. Also it says that it decrypted successfully in the app but there is absolutely no difference.. Is my file wrong? If not then where is the decrypted file saved?

I managed to extract a CIA without issues through this guide. However, when I try to rebuild the CIA (no matter whether I make any changes to the extracted files or leave them untouched) I get an error from the makerom.exe: "Application couldn't be started (0xc000007b). Klick OK to close the application."

Any clues on how to fix that? I only wanted to change the Title ID on a CIA and this is proving to me a much bigger hassle than I expected...

I am having this problem as well.

Reason is its missing the major entry in the build. The exe is just a bat file.

Change the following lines.

Code:

set /p OutputRomCIA="Write your output .CIA filename (without extension) : "
set /p MinorVer="Original minor version (write 0 if you don't know) : "
set /p MicroVer="Original micro version (write 0 if you don't know) : "

to this

set /p OutputRomCIA="Write your output .CIA filename (without extension) : "
set /p MajorVer="Original major version (write 0 if you don't know) : "
set /p MinorVer="Original minor version (write 0 if you don't know) : "
set /p MicroVer="Original micro version (write 0 if you don't know) : "

Code:

"makerom.exe" -target p -ignoresign -f cia %ARG0% %ARG1% %ARG2% -minor %MinorVer% -micro %MicroVer% -o %OutputRomCIA%_Edited.cia >NUL 2>NUL

to this

"makerom.exe" -target p -ignoresign -f cia %ARG0% %ARG1% %ARG2% -major %MajorVer% -minor %MinorVer% -micro %MicroVer% -o %OutputRomCIA%_Edited.cia >NUL 2>NUL

Now when prompted enter the full version number.

This seemed to affect the problem, although the conclusion was ultimately the same.
"makerom.exe: Application couldn't be started (0xc000007b)"

Heck, just running makerom.exe itself causes the error.

The SetupUS.exe video is unavailable so I can't download it.

Nevermind. Found a solution that works for me

I'm getting ucrtbased.dll and vcruntime140_1.dll not found when trying to rebuild cia. I have reinstalled and uninstalled visual studio redistributable 2010-2017 but it won't work.

I have a decrypted 3ds game that is simply not extracting.

https://prnt.sc/13g81db
I don't know what I did wrong or why the RomFS won't extract. Any help or am I shit out of luck?

All decrypt games .3ds (for citra) created incorrectly.Game decrypted but the crypto flag(in NCCH) remains the same original. The utility sees the flag and carries out decryption of an already decrypted game, in other words, on the contrary, it encrypts

Nah, it was decrypted the whole time. I just used Version 9 and it worked perfectly (:

using makerom with elf i can make a .3ds rom, but gateway won't load it, i've done everything i can think of, even using decrypt9 didn't work, shows up fine within gateway loader, however it won't load the rom into the cart

ive tried every makerom version, all the way till 2014

thanks to the flashcard and hardware extension haters now i cant figure out how to write my own home brew and run it using gateway, because of a brick i have yet to encounter.

i know it definitely works, as i ran other .3ds based home brew fine

Nice, this was very useful

I am currently trying to rebuild a cia but running into some issues. During the rebuild, it tells me that two dll files are missing (VCRUNTIME140D.DLL and UCRTBASED.DLL). If I get those two and put them in the right folder, the error message goes away, but then it says that makerom.exe has an error and cannot be started. What could be the issue here?

Cakekey · Jun 21, 2021

I've been attempting to rebuild my CIA, but the output files are only 1 to 15kb(compared to the original CIA being 1.7gb). I haven't moved any edited files from their original file paths, and the toolkit itself never indicates any errors with the process. It just keeps spitting out what are essentially empty CIAs.

Has anyone else experienced this?

try using the 3dsbuildermod.exe in the extra tools folder, that worked for me.

Also having this issue.

I tried taking all the extracted files/folders and rebuilding the .cia with some older HackingToolkit versions. 11 and 10 had the same problem. 9 appeared to work, but no .cia file was created (I'm guessing because of a difference in the encryption process?)

I also have the same issue. If I try to build a .3ds file, I get a 0kb file, if I try to build a cia, I get DLL problems, and if I add them it will get the 0xc000007b) error.
So, is there ANY way to create a rom? if not, is there another program?

There are older versions available at OP's Github link. Try version 9, which was the last version before it became HackingToolkit9DS. The main difference is you'll need to decrypt any roms yourself, but I've never had any program errors like with versions 10 to 12.

Okay so- I'm not sure why but I'm not getting the folders extracted at all, it gives me all the .bins files but nothing else. What am I doing wrong/how can I fix it?

Lufvave · Sep 22, 2021
