Encrypt ROMs

[Elfish]

Hello!

This might be a odd question.
I'm currently in the need to encrypt a decrypted 3ds rom.

I've found 3ds tool which seems to be able to do the job.
I sadly fail with the command line syntax

Anyone can point me in the right direction?

Regards

You can't just "encrypt ROMs" that have been decrypted. You'd need a private key by nintendo for that.

GodMode9 can encrypt titles. But what are you doing that requires an encrypted title?

I'm following the no-intro encrypted dat. Feels purer and more orignal to me.
Those missing titles were only available decrypted.

I found a solution for my problem.
There's a tool called NDecrypt (https://github.com/SabreTools/NDecrypt), that offers easy access to encrypting and decrypting roms. All you need is a keys.bin or aes_keys.txt file. Encrypting a decrypted rom matched the no-intro dat just fine .
