Nx2elf Patched Jun 2026

The Nintendo Switch operates on a proprietary executable format known as NXO (Nintendo Switch Executable). When you compile a piece of homebrew software (like a media player, a port of Doom , or a save manager), the final output is not a standard .elf file (Executable and Linkable Format, common on Linux and Unix systems). Instead, the Switch toolchain produces an .nro (Nintendo Relay Object) or .nso (Nintendo Switch Object) file, which contains encrypted and signed sections specific to the Switch’s Horizon OS.
