The game’s executable code (usually a file named main ) is located within a folder called exefs . You can use tools like hactool or NSGameManager to extract this main file from the game’s .NSP or .NCA files.

When developers compile software for the Nintendo Switch, the final binaries are packaged into proprietary formats: Used for main game executables and system modules.
: Creating custom patches for games like the YouTube app or specific retail titles.
In IDA, this is finalized via Edit -> Patch program -> Apply patches to input file . 4. Re-packing the Patched File
Modifying a Switch game often involves patching the main NSO file within a game’s Exefs . Here is the step-by-step process: 1. Extract the Binary
This command decompresses the file and creates a cleanly mapped main.elf file ready for static analysis. 3. Analyzing and Patching the Code
ARM64 instructions are strictly fixed at 4 bytes (32-bits) in length. Ensure your patch size perfectly aligns with standard 4-byte intervals to prevent fatal processor alignment exceptions.
"nx2elf patched" isn't typically a single, separate program, but rather a description of a that involves: Extracting a game's NSO/NRO file from an NCA/NSP. Converting the NSO to an ELF using nx2elf .
Newer homebrew applications embed icons, JSON metadata, and romfs data differently than older versions. The original tool often crashes or produces corrupted outputs when encountering these modern assets. Patched versions update the parsing logic to handle these structures gracefully. 2. Correcting Segment Alignment and Memory Offsets
Let’s break these down.
Once converted, the .elf file is imported into an interactive disassembler like IDA Pro or Ghidra. In this environment, reverse engineers find target functions (e.g., bypassing a token check or altering game logic values).
This "strips" the Switch-specific headers and hashes, producing a file that standard reverse-engineering software can read. Perform Your Edits
