Gaming Decrypt without trimming a 3DS file

[CommanderCool]

Is there a tool or utility which will do this? I want to match my ROMs with no-intro's archive, so that's a thing.

If you're trying to decrypt a .3DS that you've already dumped, this may work:

EDIT: This doesn't do what I asked in the thread title.

You could alternatively try decrypting it with Godmode9 on a 3DS.
I don't believe that will trim it.

It does trim it if you go and use the all-in-one megascript to attempt a dump and decrypt.

You dont use the megascript. You use https://3ds.hacks.guide/godmode9-usage

I've never seen these options in the times that I used them. I'm going to try reading through and telling you the results. Thank you for your swift replies btw!
