Or, you can ask ChatGPT to do it.
That's what I did trying to follow all these instructions

I did it yesterday, and I was honestly just shocked that it could all this time

It may do some things wrong, so you need to be very tight on your instructions.
So, export the save file. Tell GPT you want it to edit it. Give it the file. Wait for it, cause it may not give you a prompt till it's done.
Then, that's it. You can then download the file after it's done, then import it to cog demos.
