Got a giant CKAS 6DOF base, now what?

I picked up a giant used CKAS W2 base, it's the 480kg one. Runs on 220V, it's BIG. But it's very bare, literally just a Y shaped plate of steel to bolt down to. It was an excellent deal that couldn't be passed on.

It had a servo control that burned out, I replaced it, and now it's back running.

I've bolted up a seat and I'm starting to breaboard some stuff on it, it runs DCS like a champ with the "native" drivers, and is a lot of fun in VR, but I also want to run some more low end games like "City Car Driving" but there doesn't seem to be any native support.

Now, I don't really want to say anything bad about the site and the software, but navigating and understanding the business and licensing model is harder than figuring out the American health care system and about as convoluted, plus the odd and disconcerting "coins" not to mention the workflow (although somebody posted a nice block diagram) and by the way, what's the relation to the seemingly defunct and hardly working x-sim.de website? Anything? Also, did I see correctly that somehow there's some kind of subscription somewhere? I really hope I'm wrong on that.

Here's the rig. No VR motion compensation aside from mounting the tracking cameras on the rig itself which is mostly OK actually. But it's an original RIFT, which there are many better headsets out there, but inside-out tracking is going to bite me and I'll need to compensate.

At some point it will probably be an OpenVR solution with a "virtual tracker" that comes out of the SimCOR UDP stream, but that's for the future.

It looks like some people have some CKAS systems running in the community, but I also saw some unresolved or at least undocumented drama about what's considered a commercial system or not, re: licensing.

I need certainty when it comes to spending money. I don't have any problems with people monetizing their work, that's great, but I need to understand it and I don't like surprises.

And I want to play that stupid driving game in my garage.

OK great, so does this mean my post won't be allowed to be...posted? because I link to the CKAS website?

This is the busted drive in question. The MCU upper left mounted at a 45 angle wasn't coming up, was in some odd boot loop. 24V and 5V rails were fine. Nothing looked burned, the big caps were checked and were within 5% of rated value. I suspect that the oscillator wasn't starting or by some freak thing, the chip lost its firmware load. Anyway, $600 later the machine is back.

That might be true.
Communication is accomplished directly from a USB serial port, with commands coming in formatted as plain comma separated text at however many hundred Hz it can manage (for smoothness) and I don't imagine UDP is much different. It works pretty well - a .lua file is set up in DCS for example, and the game then formats UDP data that goes out to the localhost version of the SimCorDX software, which is little more than a glorified UDP to Serial bridge in our case.

In short, the platform is quiet easy to talk to (even with an Arduino!!) But until I try it, the notion of it "just working" from xsim from a couple of people doesn't hold a ton of water for me.
