So in any cases the image will be stretched and the character will look "fat"? is there something that fixes the aspect ratio?
"Force Widescreen" Tries to hack your game to render in 16:9 instead of 4:3 so things aren't fat
"WiiU Widescreen" just stretches the resulting output to fill the screen. If you have both of these options on and your characters look fat or the HUD is all screwed up, your game won't properly support widescreen and you'll want to force 4:3 when building your game with the script.
