(Suggestion) Convert titles back into Decrypted 3ds format #105

Closed RinMaru closed 7 years ago

RinMaru commented 7 years ago

so with the new cia feature would it be possible to convert stuff into decrypted 3ds files for Citra?

ihaveamac commented 7 years ago

not needed, you can extract a decrypted CIA and add ".cxi" to the end of the first content.

RinMaru commented 7 years ago

plz explain this process if you will

ihaveamac commented 7 years ago 
ctrtool --contents=contents game.cia

... then add ".cxi" to the file that starts with "contents.0000"

RinMaru commented 7 years ago

cant get ctr to start

ihaveamac commented 7 years ago

why doesn't it start? how did you try to start it?

RinMaru commented 7 years ago

ok it starts if i launch it in cmd but im still confused. say i have a cia file still encrypted or a title on 3ds im going to convert back into a cia how do go about decrypting it and using crt tool to make cxi?

d0k3 commented 7 years ago

Convert SD to CIA -> Decrypt CIA (deep) -> use makerom or CTRtool on PC to do the remainder of the conversion.

As an additional hint, CIAs created via the SD to CIA converter will be encrypted (if the original source was encrypted). Thus, you will want to deep decrypt the CIA first. Also, the conversion from CIA -> NCCH/NCSD will not be in D9, as that one is not exactly trivial and requires to re-generate certain data from scratch.

Closing this now.

  1. Use SD Decrypter to dump decrypted .TMD and .APP
  2. Copy .TMD and .APP to PC
  3. Use SDto3DS to convert them into .3DS
  4. Use NCCH/NCSD Decrypter to decrypt .3DS Done.

... Or just use the new SD CXI dumper ;)
