As other people have pointed out: &quot;Modding&quot; in Minecraft is literally replacing the original Java bytecode with your own. This is why the idea of a Minecraft launcher took off; replacing binaries with modified versions is very dirty and very difficult to do if multiple things are touching the same file. I hope that this C++ version is the impetus needed for the forever-promised-never-delivered modding API to finally take shape. Then I don&#x27;t even care what the underlying technology is.
