Ghidra CTR Loader

This is a Ghidra loader for Nintendo 3DS executables.

This fork is based on the original Martmists-GH/ghidra-ctr-loader by Martmists. Original copyright and BSD-style license terms are preserved in LICENSE.txt; later maintenance and 3DS decomp workflow hardening in this fork are by Raikaru.

Features

Currently supports:

• CXI Imports
• CIA Imports (decrypted only)
  • Currently only imports the first container
• CXI/CIA ExeFS .code imports with NCCH ExHeader code-set mapping, .bss mapping, code-set labels, ExHeader metadata, dependency names, and SVC comments
• CRO Imports
• CRS Imports (from CXI/CIA only)
• CRO multi-file analysis (i.e. linking imports and exports together)

Planned:

• Deeper relocation validation and SDK/library signature coverage
• Support for multiple .rodata/.data sections in static.crs
• CIA Imports
  • Support for multiple containers
  • Support for encrypted containers

Known Limits

• Encrypted 3DS containers are not supported.
• CIA imports currently expose the first NCCH content.
• CRO/CRS import/export linking is available, but module-specific validation should be done per title before relying on linked externals for naming.
• Private game files, extracted ExeFS/RomFS contents, and local Ghidra projects must stay under ignored .local-test/ paths.
