How to patch Nintendo Switch Applications in IDA - GitHub Gist
Extracting the "main" NSO from a game using tools like HACTool or NxFileViewer. Conversion: Running nx2elf to turn that NSO into an ELF. nx2elf patched
A "patched" version of nx2elf often refers to community-modified builds or workflows where the resulting ELF file is specifically prepared for binary patching in tools like or Ghidra . What is nx2elf? Nintendo Switch applications use custom binary formats: NSO: Standard executable files found in game data. How to patch Nintendo Switch Applications in IDA
In the world of Nintendo Switch homebrew and reverse engineering, is a pivotal utility used to convert Switch-specific executable formats—primarily NSO and NRO files—into standard ELF (Executable and Linkable Format) files. What is nx2elf
Loading the ELF into a disassembler (like IDA Pro), locating the specific function to change, and applying the "patch" (modifying the raw bytes).
Because most standard reverse engineering tools cannot read these formats natively, developers use nx2elf to "decompress" and "reconstruct" them into ELFs. This reconstruction includes vital metadata like dynamic symbols ( .dynsym ), relocation tables ( .rela.dyn ), and Global Offset Tables ( .got ), which are necessary for understanding how the code functions. The "Patched" Workflow: Why Use It?
Relocatable files typically used for homebrew applications.
