@DenJohn It always had that, but it's a hack that doesn't work with Wine... I don't know why they announced it like that, it's misleading.
As far as I know the only thing that changed in the new release is that the 16K hacks are now enabled at runtime instead of having to do a special 16K build at compile time. But there's no way to make those hacks fully compatible, that's why we're working on microVMs. If it were possible to do cleanly without a VM we wouldn't be spending all this time on VMs ^^
Regular 4K box64 in the krun VM would be interesting to compare to FEX though!
