The SMS Tilemap is fast, but less flexible than a bitmap screen. A 256x192 screen would need 768 tiles to simulate a bitmap, and we have only 384.

BUT by using 2 tricky palettes, and 'splitting the bitplanes' we can use each tile twice so we CAN simulate a 4 color 256x192 screen!

As always, this Video lesson matches the text lesson on my website, and you can get the source code as well...
