I can't speak to the quality of that hack, but it does sound like a godsend. In the original, you have to open the menu to talk to someone (Menu -> Talk To) or to open something (Menu -> Check). Yes, they're separate commands. You can't talk to a chest, and you can't check a person. If you're too far away, it pop up a dialog saying "No problem here" that you have to dismiss and navigate the menu to try again. It's crazy annoying.
