3DS-rom-tools VS ILSpy

This is the one I have been using (https://github.com/ihaveamac/3DS-rom-tools/wiki/SeedDB-list). Make sure to put it in the same folder as the decryptor.

I use the custom-install program to install games, where you need to provide your own seeddb, so I downloaded one from custom-install's maker - https://github.com/ihaveamac/3DS-rom-tools/wiki/SeedDB-list

For open-source tools, Project CTR includes ctrtool to extract many 3DS formats including CIA, and makerom to build an NCCH, CIA, or CCI file. It's a bit old so I'm not positive it'll work exactly, but there's a guide on extracting a CIA using ctrtool and 3dstool, then rebuilding it using makerom and 3dstool.

Basically, you would need a tool to unpack an FE15 3ds file, load the files into Paragon, edit the skill on everyone you want and then repack the edited files with the rest of the unedited files from the game, and play. If you're wondering how to unpack and repack 3ds files you may find this resource on github to be useful.

First, go grab this: https://github.com/icsharpcode/ILSpy. It's a decompiler that will break Rust down. Hope you like C#.

If its a C#/.NET exe you can use ILSpy to get the source code https://github.com/icsharpcode/ILSpy

Well, it might not be exactly what you're asking for, but ILSpy lets you choose what version of C# you wish to decompile an assembly to. This is great for learning how a specific feature used to be coded in C# prior to some new syntax/compiler feature being added.

You will thoroughly enjoy this, then.

I've only used their GUI frontend myself, but ILSpy is also available as a library and command line tool.

As you can see IL code is not exactly human readable, and it's also quite verbose. If you want to have an idea of how your code looks like in IL you can use a decompiler tool such as JustDecompile or ILSpy.

Take a random piece of C# software, run it through ILSpy, and be amazed at the results.
