Alternatively, you could do the opposite of what many Amiga people do, and use a real A500 mouse with a bus-to-serial mouse adapter. Yes, there are/were such things, because in the dawn of the Clone era, when they were trying to catch up with the Amiga, there were both Amiga style and serial mice. Micro$oft backed the serial mouse; guess who won. However, to push their agenda, Micro$oft actually manufactured bus-to-serial mouse converters, and I have one.
