You used "16:9" every time, I guess one of them should be "4:3".
I suppose you wanted to say you try to force the game in 16:9 but they display in 4:3, right?
You are launching USBloaderGX from the Homebrew channel or a forwarder?
If you launch something from HBC with WiiU System menu 4.x, the aspect ratio is forced to 4:3, you need a fix to launch homebrew and games in 16:9
there are two methods :
- HBC forwarder, by JoostinOnline: a channel which launch HBC in 16:9
- Aspect Ratio Fixer, by Tueidj: a homebrew to launch when you are in HBC to fix the ratio and return to HBC, before launching another homebrew.
If you try to force 4:3 but it display in 16:9, then it's the same problem as muyfa666
I still haven't check this issue.
