{{obsolete}} A simple script to patch the .text sections of nso files and reassemble them. Here are some sample videos of what it can do: *https://twitter.com/tesnos6921/status/1003007238984921089 *https://twitter.com/tesnos6921/status/1003365767449018373 ==User guide== Python 2.7, requires lz4 module to be installed. 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) <code>location:codepatch</code> ** Example: <code>2E8:21008052</code> *Then run "python patchnso.py main patch-file-here output-file-here". *Your patched file will appear and you can put it under /atmosphere/titles/title-id/exefs/ on your sd card, renamed back to "main", with the other files from your extracted exefs and you have now patched your game. ===Sample patches=== Some sample patches are included (made for Super Mario Odyssey Version 1.2.0) which you can try out. Make sure it is on the correct version. Sample patches nclude: *Don't Lose Health. *Near-Zero Gravity for Normal Jumps. *Raise Coin Limit To 65536 (Untested). *High-Power Long Jump. *Hyper Walking Speed. *Stop Player From Dying (Allows walking on acid and lava) (Credit to SimonMKWii). *No Damage for Running out of Oxygen or Staying in Ice Water (Credit to SimonMKWii). ==Credits== Thanks to switchbrew.org for docs and the atmosphere team for exefs patching so early. == External links == * GitHub - https://gist.github.com/tesnos/66d17f694ef570ae8011a53e97ce437d * GBAtemp - https://gbatemp.net/threads/patchnso-py-a-script-to-patch-the-code-of-games-more-easily-before-layeredfs.506152/
