Log.png - width=413 height=481
0.3.0
* Adds support for native plugins.
* Code refactoring.
0.2.2
* Fix mods made for Mono Patcher 0.2.0 not working anymore.
0.2.1
+ Added ability to manually JIT recompile methods.
* Now, by default, automatically applies method replacements without having to call MonoPatcher.PatchAll(). This behavior can be changed by mod developers.
* Removed a debug log string generated by vanilla TS3 that could slightly slow the game down at times.

Mono Patcher is a library that allows Script Modders to replace Sims 3 methods with as much compatibility as possible - No need to create core mods anymore to replace game functions.
Features method replacement and editing of C# IL instructions for advanced users. Also removes the need for Instantiator tuning XMLs as it has a custom mod loader that runs early, allowing you to replace most code before it runs.
For advanced users, it also lets you call custom native/C++ code from your script mods, allowing you to further extend the game's functionality.

If you're a script modder looking to use this library check out the GitHub Repository. It includes an example project plus a Wiki with tutorials and examples explaining how to get started and use its features.

Included in the download zip are "Packages" and "Bin" folders.
For the Packages folder, simply drop its contents into your Documents/The Sims 3/Mods/Packages folder as with any other Script Mod.
For the Bin folder, if you're on Windows head to your Sims 3 installation folder -> Game/Bin and drop the contents inside, alongside your game executable. If you're running on, say MAC instead of Windows you can skip this step as it's not compatible - Mono Patcher will still function without the Bin files but won't have all features available.

If you get an error on startup, chances are you need to install the following:

This mod is still in an early state - features will be added in the future to make things easier and better for modders.

About Me
Some further elaboration on my TOU:
Please direct to my original uploads as much as possible if you want to redistribute my mods, ideally link directly to the original upload so that people can stay up to date and get them directly from me.
I’ve made updates for or transformative works out of old resources (tools, mods, etc.) myself. I’ve made them with the intention to help preserve and maintain resources that are still useful to the community today, but whose creators have moved on.
