I'm not sure what I'm doing wrong here, but I tried extracting a CIA but no file is getting extracted in the same folder. It does say the extraction completed though. Using the v12 from Github.
Edit: So it looks like I have to run the setup.exe first before running the toolkit. However, I ran into a ucrtbased.dll/VCRUNTIME140D.dll missing error when I tried to repack the CIA. Anyone know which redistributable I have to install to fix this?
I had this problem as well, the tricky thing is as far as I know you cannot just install this file through a redistributable (as it is a debug file "vcruntime140D.dll" instead of "vcruntime140.dll", the latter being what you get in the redistributables). You can download it from a site called dll-files dot com (which I can't link to as I'm not allowed to link things in my first 5 posts apparently), which also provides ucrtbased.dll, another debug file it started asking me for after I provided vcruntime140d.dll, just in case it asks you for that as well. The site also explains where you need to put them for the different versions of Windows.
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 now also having this problem, I've tried everything I could see online to fix it but nothing has worked so far so please let me know if anyone is able to help here.
Edit: Here are the results of extracting and rebuilding on different versions of the program:
Version 11 - After rebuilding, it outputs: "The filename, directory name, or volume label syntax is incorrect.
Creation done!" This is a lie. nothing is created
Version 10 - It...works? At least, it outputs a file the same size as the original with no errors. When testing it on my 3ds however, it does not work. FBI fails to install it, giving the error code 0xD8E08025 which apparently usually indicates an issue with your SD card, but this is not the case here
Version 9 and below - It successfully rebuilds an 83kb file, just a little bit smaller than the ~400mb one I had started with
