Hey...
Sorry but the original post actually dosn't define much...
Suggestion... When asking questions... Try to really ask a question...

Another suggestion...
Take a look at the Loopix Mysty Mood project.
It is a good way to learn about 3dgs...
It has good information with a tutorial...
It can be used as the template for your game...
The code is documented well.

Go to
http://www.loopix-project.com/
Then click on the "Easy" button on the left...
Then click on the "Templates" button above...
Then download the Lite-C version...
Then look at the project and read the documentation...
All the data is free to use in your games...
