Decryption Failed

[syntheticgerbil]

Using the newest version of 2.0.
First the program didn't want to run from command line until I was able to obtain libstdc++-6.dll from a random DLL site (tried to choose a 64 bit one). I placed that in the same folder as the exe.
Then it asked for libwinpthread-1.dll and libgcc_s_seh-1.dll. Also got them from a random DLL site, 64 bit. Placed them in the same folder as the exe.

Now it runs, however I get "Decryption Failed" error.

On cmd line it reads:

|_v2.0|
Reading 4B513945.bin
Reading resources/movable.sed
Dumping msed_data.bin
Scrambling keys
Decrypting header
ERROR:Decryption failed
Hit Enter to close

I've tried this both with the movable.sed output from gm9 on the Target 3DS. And a movable.sed created with Seedminer. Same error either way. Same issue with different .bin files.

Can you try building from source on your PC? My release bin didn't work on my PC either (it did at one time) but the built exe worked.

If no luck there, you can also try running the python script in the repo, it's functionally the same.

I think that's all over my head. I tried to download python and mess with copying and pasting the code but I have no idea what I'm doing at all. Thank you either way. Sorry about the bother

If you're trying to decrypt an export with a movable.sed from a different system from where the export was originally dumped, it wont work. At least that's what it seems you're trying to do from reading your posts on discord.

I have the same error message whether I try to dump a .bin from the previous 3DS that was unhacked and I do not have the movable.sed for or the one I have recently saved a DSiware game to the microSD card and also try to dump it from the hacked 3DS the movale.sed came from.

However if it's not possible at all to dump a .bin from a 3DS where there is no movable.sed available then I won't be able to achieve what I'm looking to achieve anyway.

I thought it was possible based on this reddit thread and the main response: https://www.reddit.com/r/NDSHacks/comments/otnpq0/can_you_backupcopy_save_data_from_legitimately/

However they are using Tadpoli, which I was incorrectly using first, and I'm trying to transfer saves from .bins from an unhacked 3DS not DSi. So I guess that's my issue and I'm barking up the wrong tree. Hopefully one day there's a way to dump .bins from a DSiware exported to SD card on an unhacked 3DS.
