It even still calls the OutputDebugString API, so when you run the game with a debugger attached, you can see all these log messages!

Here's a selection of some funny messages:

"You madman! You're running a 24-bit desktop! It'll be slow.."
"Created Too Many Models! TALK TOO [sic] TIM NOW!!!"

I'll probably put this on pause for a little bit, but intend to continue at some point - I'd like to at least get 3D models displaying in the level viewer, and ideally figure out the lighting system.
