So I'd been playing around with the Xbox version for a while, and now that there's a PC version more people can actually follow along. So here you go:
If you do a 4-byte search for "007747D4", you should get one result, which will be the information for the current player. Here's a quick labeling of cool things:
You can assign a hotkey that adds to that Z float and you can essentially have a Jump button.
Those scale floats, well, http://steamcommunity.com/sharedfiles/filedetails/?id=191046272
Update: The new value up there is better to search for and works both indoors and outdoors, and any character.
Then in the savefile, located in the game's \savedata folder, has 2 things to point out:
Offset x5CA is the character, your choices are:
2 Child York
3 Raincoat Killer
I should note that anything not York will probably not be able to open doors, among other things. But for a good amount of cutscenes they work add some silliness; http://steamcommunity.com/sharedfiles/filedetails/?id=191015359
Then at xCBF9 would be your current room, though many times your current coords will start you under the world and you'll fall to your death. Don't really have a list of good rooms, sorry.
The .DLC files in \addon are textfiles and the "bonuses" each suit/whatever brings can be tweaked. (PARAM0-PARAM5)
