* Finally, you should make a local copy of the `main` file in Ghidra. Right click on `main`, select Copy, then right click again and select Paste.
* This is so that you will be able to save changes that you make while decompiling, as you don't have write access to change `main` itself.
* Additionally, Ghidra has a bug that causes the remote version of `main` to be extremely slow to use if you only have read access, so you should still make a local copy even if you don't intend to change anything. The first checkout of `main` will still be slow, but opening the local copy in the future should be fast.
Now you have Ghidra set up and ready to use.

> Some actors that aren't decompiled may have already had their struct defined in our Ghidra server by someone else in the past, in which case you may be able to skip this step. But this is not the case for most actors.
In objdiff, pick one of the actor's functions (one with "create" in the name would be good to start with). Then open the `main` program in Ghidra, press `G` and type the function name (e.g. `daWall_c::CreateInit`) to go to that function in Ghidra. If the struct hasn't been properly defined for Ghidra, the function may look something like this at first:
