I used Eltech's Exagear with the Raspberry Pi 3 computer. I know how to use the X86 user space that is installed on top of the Raspberry Pi operating system. Box86 should be more up to date compared to Exagear. With Exagear, you did not have graphics acceleration. I tried to run Command & Conquer Tiberian Sun with Exagear. The game was barely playable, because the old Windows games used a single CPU core. The old Windows games were not multi threaded. I watch the Pi Lab videos from time to time, very interesting project. I'm more interested in Linux source ports compared to PC or console emulators.
