Lets take a look at the simplest Draw routine, the one which writes straight to VRAM - intended for Double Buffered screens.
We'll also look at the 'expanders' which convert a 1 byte per tile tilemap to a 2 byte one - This is used for expanding the player sprite tilemaps into the cache for drawing, it also X and Y flips them.
As always, this Video lesson matches the text lesson on my website, and you can get the source code as well...
