Memory map:

$0000-$00ff = zero page
|

$0100-$01ff = stack
|
|
|

$0200-$03ff = ???
|

$0400-$07ff = lo-res page1
|

$0800-$0bff = lo-res page2

$9000-$93ff = tiles (1k)

tiles are 2x4, or 4 bytes each
|
|
|
|
|
so in theory can have up to 256 of them

but if we want data to fit in one page then 64 it the maximum
