Memory map:
$0000-$00ff = zero page
$0100-$01ff = stack
$0200-$03ff = ???
$0400-$07ff = lo-res page1
$0800-$0bff = lo-res page2
$0c00-$0fff = background image
$1000-$1fff = loader
$2000-????? = code
$9000-$93ff = tiles (1k)
$9400-????? = big_tilemap (10k)
$BC00-????? = tilemap (1k) 10x16
tiles are 2x4, or 4 bytes each
so in theory can have up to 256 of them
in 16x16 grid
tilemap is 256 wide by 40 tall = 10k
Tiles:
hard tiles start at 32
