If you dont know tiles check out
www.directx4vb.com /DirectX7/Direct
Draw/Tile based game (or smth like that) Its for dx, but you'll get the
picture. It doesnt however scroll. On the otherhand
www.rookscape.com/vbgaming/ should have a "smooth scrolling tiles"
tutorial. One thing about it though.. its EXTREMLY complicated and
hard to understand. Also, it can be a bit hard to do collision detection
with it...
