@Flight Well I'm not dead, the sky is up and I got my Pro Controller working with my PC in the end.
If you remember from last month, I was having an issue where my default drivers kept reinstalling and taking the place of the new Toshiba ones. I first tried turning off auto-detect drivers in the advanced start up settings, yet the drivers still kept coming back. Then you suggested that I stop automatic driver updates in advanced system settings, and that worked!
At least- for little while. When I restarted the computer, Toshiba Bluetooth Stack would no longer recognize any Bluetooth signals. I was in a position where I would have had to reinstall the damn thing every time I booted up. However, I stumbled across a solution. While searching to see if I was really using the latest version, I discovered that Toshiba made different drivers that you could use depending on the manufacturer of your Bluetooth device. The weird thing is these were not listed on Toshiba's page where I got the old ones and can no longer find. I installed the ones for Broadcom, without uninstalling the old ones, and after that, Toshiba Bluetooth Stack worked like a charm.
However, I had another problem. WiinUPro needs another program, called vJoy, to read the stick movement. So downloaded the latest version as instructed, but it didn't work. Turns out it only works with an older version. So I got that, and made some progress. I tested it on Dolphin, put it wouldn't let me select the controller. So then I just downloaded WiinUSoft, which tricks your computer into thinking the Pro is an Xbox controller. And I still use that to this day!
So that, ladies and gentlemen, is how to install the infamous Toshiba Bluetooth Stack.
So, while I was gone the site got a pretty fresh redesign. I kinda like it.
