Keep in mind, as other's have said, this version has a debug menu in it that does most of what the cheat tables and trainers already do. That being said, I have the legit version of the game and downloaded the dev exe + data folder to copy over my stock version of the game for this functionality. What I discovered is saves from retail also work on the development version, so you can use things like positional coordinates to port to retail. A proper location modifier for instance.
There may not be much you can add to this version that isn't already built in, but damn is it a good tool to port debug features to the retail game.
