Yep, no one is understanding the issue here. Thank you Statyk.
Okay, let me re-clarify.
The Oculus Rift is NOT supported mainly because the HPL Engine does not support it. It's not like you just input a little program and it'll work no, but the whole engine have to re-written from scratch.
You can find explanations from posts above and the pages before. Like it or not, AAMFP WILL NOT have Oculus Rift.
But it's currently unknown for HPL3 so maybe HPL3 supports it. I dunno. Maybe it will or not.
