Homebrew Batch CIA 3DS Decryptor - A simple batch file to decrypt CIA & 3DS

[anotherthing]

works for .3ds file but how to convert .3ds to .cia?

There's a nice little tutorial on how to do it.

I put my rom in the folder with the decryptor, but once I run it the message immediately says it already finished. But when i check, my rom was never decrypted. I tried renaming the file to see if that was the problem but nothing worked.

When I run the decryptor it doesn't leave a decrypted version of the file afterwards.

OMFG Dude, I've been trying to use the file against Chibi-Robo! games and you were exactly right. That really screwed with my head so much. Yeah, deleting the exclamation points was the answer. What a stupid error!

There asre still plenty of files which cannot be decrypted. For some reason it's mainly files that have "World" in the title, such as "A-Train 3D (World).cia"

Is there any reason for this, and more importantly, how can I actually decrypt these files?

EDIT: other files give me the following error:

[...]

struct.error: unpack requires a string argument of length 4
Failed to execute script decrypt
[SETTING ERROR] Argument "-rsf" is required
