It works because the mechanical interfaces are translated by connector adapters and the electrical signals are translated by a little controller embedded in the PS2-to-USB adapter. I chained together a full sized DIN-to-PS2 adapter to a PS2-to-USB adapter that handles both the keyboard and mouse. I liken WINE somewhat to the way I got my ancient Northgate 101 mechanical keyboard and PS2 mouse to work with a Raspberry Pi. I say fragile because if the app developer updates their app to use different calls, libraries, or system services on the native platform it will probably no longer work with WINE until an updated set of shims and adapters is built. This makes their adaptation, which is not emulation (as the WINE name asserts), very application specific and (in my opinion) very fragile. Basically WINE is installing software shims and adapters to replace only the native operating system dependent calls, libraries, and services that the specific application actually uses with ones that work similarly on the non-native platform. WINE is focused on getting individual apps running across platforms. WINE/Crossover is targeting a different set of use cases than Parallels and VMWare.
