I have a very tricky and somewhat strange question about VR games package.

Guys, I have a very tricky or somewhat strange question about the VR games package.
I am now able to package VR games successfully. It can also run on the HMD like this


You can watch the 360 views in HDM

But now for some technical purpose, I have to package the game into a flat-screen containing 360 views of the scene, like this:

it can be not a VR game, just the game screen needs to be such a VR screen tiled open, I don’t know if I described it clearly.

I just need to package the game into such a 2D screen instead of outputting video or images.

Or is there a way to convert a VR game into this kind of screen?

Thanks so much for your help.
