Sysmodule for injecting custom codes into retail Nintendo Switch games, by default it injects "Core" which includes many useful features known as NX-FPS (tracking game performance statistics, unlocking FPS) and ReverseNX-RT (switching between docked and handheld graphics profiles). Sysmodule also manages custom refresh rates in both handheld and docked modes.

This sysmodule targets more common approach, so basic compatibility with all games is a priority. If you want to inject your own code for specific game I recommend much more powerful code injection framework - exlaunch.

Original sysmodule was created by: https://github.com/shinyquagsire23

This fork includes many new features (aforementioned NX-FPS and ReverseNX-RT), compatibility fixes, and beside plugins support also supports patches for easy way to edit common functions.

Tools utilizing SaltyNX:

• FPSLocker
• ReverseNX-RT
• Status Monitor Overlay
• And more

For additional functions you need SaltyNX-Tool

Patches pattern:

• filename is a function symbol with filetype .asm64 for 64-bit games, .asm32 for 32-bit games,
• inside file write with hex editor instructions that you want to put into this function,
• put this file either to SaltySD/patches to make it work for every game, or to SaltySD/patches/*titleid* to make it work for specific game.

Examples of such patches can be find HERE.

Download newest version from RELEASES, look for .zip file with name starting "SaltyNX", unpack it.

Put atmosphere and SaltySD folders unpacked from zip archive to root of your sdcard.

Remember to restart Switch.

• Cooler3D for sharing code with me how he was changing handheld display refresh rate in his tools that were first publicly available tools allowing this on HOS. I have used that as basis to make my own function.
