I think I found a solution to the mouse pointer not being aligned right, at least for my situation. It seems that when you install this hack, then run the game the mouse will line up fine, but if you change the resolution the mouse will no longer line up.
To fix this, I removed the hack files, and opened the game and set the resolution to what I wanted. After this I closed the game, installed the hack and reopened the game. Now the game opens with the correct resolution and the mouse lines up fine.
The only issue I have now is sometimes when you close dialog boxes the screen will automatically move to the top right of the screen, but this is a minor issue.
Also, sorry if someone already covered this. I skimmed through most of the posts and didn't see anyone suggest this.
Thanks for the hack, I hate when things get stretched to widescreen and turn my ferris wheels into ovals.
