However, on the Switch, the community largely moved away from specific "patched" versions of nx2elf in favor of holistic memory dumping solutions.

Always create physical system backups ( .bak files) of your working files before running any bytecode patches in IDA Pro.
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.
If the game fails to boot, verify that your final NSO is correctly compressed and matches the original's expected size/format. GitHub README
