Usage Instructions:
- Using hactool, extract the exefs of your game.
- Within the exefsdir, there should be "main" and "main.npdm" and possibly a few others.
- "main" is the game's main nso, you can load it into IDA and create your own patches or go out and find some.
- When you have your patches put them all in a file in this format: (all values should be in hex)
location:codepatch- Example:

- Example:
- Then run "python patchnso.py main patch-file-here output-file-here".
