ctrtool, makerom and decrypt.py can be downloaded with dltools.sh

📋 Roadmap

• Decrypt .cia

  • Patch and DLCs
• Decrypt .3ds
• Rust decrypt.py rewrite (in progress)

Warning Decryption with cia-unix may fail, when it happens it is suggested to decrypt roms directly on the 3DS.

You’ll need the Crystal compiler

crystal build cia-unix.cr --release --no-debug

Dependencies can be compiled with makerom and ctrtool make files
