Here's a short little write up on getting Age of Mythology (great break down by staff here )running under Virtualbox. I'm running mac OS 10.15.4 but this should work under all platforms using VirtualBox.
Afteri some trial and error, I found that VirtualBox 6.1 wasn't working with 3D acceleration under XP (apparently it's been removed) so I had to downgrade to 5.2.
