My only experiences of playing Virtua Tennis have been on arcade machines and via emulation so this cool trick passed me by. MullTheDull discovered that when you have the Dreamcast VMU in your controller while playing Virtua Tennis, it displays a wireframe version of the match you’re playing, as well as the updated score once the point is won. I think that’s an awesome feature and it’s a shame we might not get to see anything like that again in future consoles since there isn’t much scope for dual screens (RIP Nintendo DS and Wii U, to name a few).
Apropos of nothing, I want a Dreamcast now. For science…
