Oculus Rift mode with DIY Rift (games crashing)?

[Clockrow]

Is it possible to get the Oculus Rift rendering mode to work with a Google Cardboard-like setup? I've seen a few posts/DIY HMD guides stating that Vireio will work that way, but I've also seen posts from people reporting game crashes because a default rift profile hadn't been created (which is my problem; every game crashes on launch under Oculus Rift mode). I've tried running everything in admin and VP is installed in a location without any spaces.

I'm curious because, while the DIY Rift mode works just fine, the clamped textures wrapped around the distorted area of the screen are pretty visible with my setup (I'm using an iPhone 5c with a 4 inch screen).

So, two questions:

1. As above, is it possible to get the Oculus Rift mode working without an actual Rift?

or

2. Is there a way to black out the clamped textures under the DIY Rift mode?

Thanks for any help!
