What I have

Tile based game
64 pixel tiles, RGB color
maps that are changeable and variable in size

Problem:

Maps over 80 x 80 will not appear on the screen
Chemist not programmer
Slow brain

Thoughts:

I think its a memory thing but I am not sure.
Is keeping that big DC in memory really really bad?
I dont ever display the whole DC just what you see.

Also, if I change the picture in the DC does it create a memory
hole or pointer problem. I mean without deleting it.....

Thanks
