Half-Life-Alyx-novr VS PhoneVR

It was a little while back, but try following the guide here to getting the SteamVR emulator working. https://github.com/r57zone/Half-Life-Alyx-novr

I've actually been thinking of playing it this way myself

You can play it with the no VR mod : https://github.com/r57zone/Half-Life-Alyx-novr

That said, there is a mod to accomplish this. Here's an article outlining why playing with that mod kinda defeats the purpose, which would also apply to watching a playthrough on Youtube in different ways -- either way, you're not getting close to the experience that's intended, which goes a long way to serving the story imo. But, if you'd like, you've got some options.

Meanwhile, This mod exists.

I recently purchased a VRG Pro and a Bluetooth controller to use with my Android device as a VR headset. I am having difficulty using the controller within VR using PhoneVR + SteamVR.

https://github.com/ShootingKing-AM/PhoneVR there is an free and open source version

Sort of lol. Riftcat only allows you to use it for 10 minutes at a time, unless you pay $15 one time to unlock unlimited time (which I might do.) It connects to SteamVR which is insane and does WAYYYY more than I wanted it to do! This has cause me to do a ton of tinkering, set up my xbox controller with SteamVR, and now I am looking at an open source version of Riftcat called PhoneVR. I just installed PhoneVR and have had a chance to get that working yet. I will make another comment if I get that working. If not, I will probably pay the $15 for Riftcat.
