Lol Hoping that all of you are on 56k and could not find the time to download my engine I decided to post the code for you.
Note: Just save the code below in individual files. I would however recommend you download my engine with the link above because it comes with images.
Below is the Main game code. As you can see its much nicer then my old version in the codebase and my other thread. Name this file whatever you want.
