I can't seem to get the Linux VMs running (I'm just getting a CORS error when it tries to fetch the little text file at `https://vfsync.org/u/os/buildroot-riscv64/head` for example), but the Windows 2000 one does work. Quite smoothly even.

It only allows bellard.org, not www.bellard.org. Changing the domain loads the same webpage, but with CORS working as intended.
