1. Introduction: What is nx2elf? nx2elf is a specialized conversion tool designed to transform Nintendo Switch executable formats — primarily NSO (Nintendo Switch Object) and NRO (Nintendo Relay Object) — into standard ELF (Executable and Linkable Format) files. ELF is the common binary format used by Linux, Unix-like systems, and many embedded environments, making it the de facto standard for reverse engineering tools like IDA Pro, Ghidra, radare2, and GDB.
