After much trial and error from buying various AVI compatible VR headsets, (and making a few returns for complete refunds (sigh) I actually found a good VR headset , which is compatible with old systems that use AVI. It was my last effort and the only one which added depth and 3D to the game.
The VR Headset is called Omino:
Using an AVI to HDMI converter I've been able to hook up all my old systems to the headset!
It actually allows you to add depth and 3D to the game you are playing. I've already tested it on systems such as: Gamecube, Playstation One, Playstation 2, N64, and Saturn. It's not compatible with the newer systems though, such as PS4.
I can say with much excitement: I've played Skies of Arcadia in VR! Added depth and 3D allowed me to truly appreciate the environments!
Note: Be warned though, the headset only supports a 75 Hz screen so the AVI to HDMI converter needs to support under 75 Hz screen resolution. I bought this AVI to HDMI converter and it's working Okay so far; albeit with a little bit of flicker on the screen (hardly noticeable): Portta WPETCHP AV/CVBS Composite to HDMI Converter:
***Important!!! Even though the Headset comes with a remote you can fine tune the 3D and depth better with the buttons on the headset itself. Go to menu and select Stereo, within the slider bar, Just before the image splits go back one and it will be in sufficient 3D and depth for your eyes. Also press the enter button to center or unlock the image for head tracking..
-Go to Stereo mode and give the image/screen as much depth and 3D as your eyes can handle! It truly adds another layer of immersion to the game!
-Cut some of the foam near your nose off of the headset with scissors, so your nose is comfortable and you can breath adequately.
-Any old first-person game you have will look really impressive
-If you want to spend the money you won't be disappointed. There are a lot of other systems and games that can benefit from this as well: PS2, XBOX, PSOne, Wii, etc...
