((free)): Nx2elf Patched

To streamline the creation of small, precise patches, the format was developed. Designed specifically to work with the .elf files generated by nx2elf , it offers a clean and verifiable method for patching. An SXPD file contains a header with SHA256 hashes of the original and patched .elf files for verification, followed by a simple list of memory offsets and new ARM instructions. This structured approach makes patches more reliable and easier to distribute, moving away from simple memory searches to a more robust system.

Flawlessly handles both user-land homebrew apps ( .nro ) and system/game binaries ( .nso ).

nx2elf is a tool that converts the main executable file of a Nintendo Switch game or application into the standard ELF (Executable and Linkable Format). The Switch's native format is difficult for standard disassemblers like IDA or Ghidra to read. By converting it to an ELF, nx2elf provides reverse engineers with a familiar and analyzable format, making it the first and crucial step in creating patches for performance (e.g., 60 FPS unlockers), adding cheats, or applying game modifications.

Why was this useful?

Both formats often utilize unique proprietary compression structures and omit or obscure standard section headers to optimize memory footprint and security. Because industry-standard reverse engineering applications like Interactive Disassembler (IDA Pro) or Ghidra natively interpret standard ARM64 ELF files, raw NSO files cannot simply be opened directly for advanced debugging.

During conversion, preserving function names (symbols) and relocation data makes reverse engineering significantly easier. Patched variants improve symbol table generation, preventing the output ELF file from looking like a stripped, unreadable mess of assembly code.
