I'm waiting for them to...
...run a 16-bit Windows 2 program on Windows 3.1, which is installed on top of DOS 6 that is running in a DOS emulator running inside the Amiga emulator, WinUAE, on a 32-bit Windows 10 install that is, itself, running on the 32-to-64 bridge in Wine/CrossOver on top of macOS Big Sur, on an ARM CPU that is emulating x86.
Or is that a bit ambitious?
