The true way is to have the source code files of these extensions, which if not released publicly, then only the creator of the extension has it
But let's say that you have the source files, you would need to have Extension development knowledge to actually continue working on the thing, this means good knowledge of Visual Studio IDE, C++ programming language, Fusion 2.5 SDK, and pretty good general programming skills, also for extensions like this they would need to communicate with other APIs and such, so you also have to have some very good knowledge of how they work
