You can use this to make it a 6DOF headset and try some games https://riftcat.com/vridge. Source: 11 months ago

I remember trying the demo version of VRidge ages ago, my phone back then wasn't really ready for it but still played a couple of levels of the original DooM without too much issues. Source: about 1 year ago

That's years after Riftcat/VRidge, iVRy and AMD ReLiveVR did it and finally Airlink only happened because VirtualDesktop was stealing the show, an as far as I know only existed because this engineer started it on their own, PC compatibility was very very low on Metas TODO list.

One way is with Vridge / Riftcat, which is the only program I know of which allows you to use the Flow with SteamVR. You have to install Riftcat on your PC, which can be downloaded on their website and then you have to install vridge on the Vive Flow. Https://riftcat.com/vridge Since it is not fully supported on the Vive Flow, you have to sideload it e.g., with Sidequest. You can find the apk-File in this... Source: over 1 year ago

OpenBravo POS used to be ok, it even worked with barcode readers. But you could also manually punch up a sales receipt and it would adjust on hand numbers automatically. But Open Bravo has moved on to a cloud paid model. However there a few forks from the before time, like Unicenta, but I've never used that one and can only vouch for what it was back in the day.

I would recommend going with https://opensourcepos.org/ or https://unicenta.com/. Source: almost 3 years ago

Unicenta works pretty well on a POS that I salvaged from a shop closure last year (no reason for doing so - just thought it would be cool to have one for the hell of it). Runs on Linux as well as Windows if you want to escape Windows Embedded 7. Source: almost 3 years ago

Looks like Unicenta is an alternative POS that can be self-hosted and is licensed as GPL-3.0-or-later. Source: about 3 years ago
