Only the left eye has an image on the upper screen about citravr HOT 2 OPEN

i just ran into the same issue. also it would be better if the screen can rotate.

Edit: i somehow managed to work around the left eye issue. It seems that nlpp does not support stereoscopic images, so the image rendered in the right eye should not be added offset. I'm still trying to look into the possibility of doing the rotation.

The "screen rotation" thing is not neat to be put in settings VR section, so it may be hard to get the changes merged into main branch for now, while hotkeys need extra gamepad.
A better solution may be to add a new menu UI layer based on VrUILayer with JNI, where you can lock screen/switch mono or stereo/do rotation/etc., but more changes/time/trial-and-errors/reviews are in need if it's going to be implemented that way.
If you want to play NLPP on quest right now, you can try this build. It's a debug version that won't cover your original CitraVR app data if you use a different user directory. To play NLPP with a better experience, go to Settings->VR and turn on the last two options, and you're all set up!
Note that sometimes the app may crash, not because of the mod, but maybe the double instance issue (after v4.0.0 i suppose?). Also remember that NLPP itself does not support stereoscopic images, so it's the same experience to play it with PC/Android Citra Emulator instead, except that you will get a bigger screen.
