FYI, only the person using the hacks can see the changes if you're online (as far as I know).

Correct. This is because the other players simply don't have the modified race course data, and there's no way to get it to them without them being able to hack. Like models, like textures, unfortunately.

What happens to the computer racers when they race the course?

They follow the route of Shy Guy Beach. Because everything has been made solid, it works, and they drive a fairly decent route round the circle. On the video, watch after I've finished and you can see the basic route that the CPUs try to take

Yeah, but I couldn't wait for ya to get online. I had been working all night to get it complete, I uploaded the vid at around 5:00am! Posted here shortly afterwards. But don't worry, when model hacking gets under way properly, I'll keep it updated in the same way I did for texture hacking
