I can actually play alyx now, still some minor issues to work out like how easily the system is brought up but it does seem legitimately playable hah.
Also swapped it to emulating index controllers so the position/rotation is easier to make sense of.
Some cursed control issues...
Got a lil further- wrote a SteamVR driver for it, man doing that on a device running SteamVR is really hard, constant SteamVR restarts, remote desktop was a godsend for this...
