Game Won't Start for me

I am trying to get Demon's Souls to work, but the game won't load.

This is my log.

What is it I am doing wrong? I followed some guides on YouTube that shows where I was supposed to put the Rap file. IS there something I am missing?

Don't follow YouTube guides, there's a Quickstart guide that tells you how to properly do it and also where to place RAP files

If you look at compatibility list, you'll see that's not compatible.

Only disc versions work.
