#split out blocksets into binary data files

# There's also code here to spit out asm for each blockset,
|
|
# but it's too many lines and will probably crash rgbasm.

#10:02 <+sawakita> each block is composed by 4x4 tiles
|
|
#10:03 <+sawakita> so you can see a blockset as a list of 16-bytes long arrays
|
|
#10:07 <+sawakita> 4 bytes for each row of the block, left-to-right, top-to-down
|
|
#10:08 <+sawakita> so first byte is top-left tile
|
|
#10:08 <+kanzure> top-left tile byte is a tile id?
|
|
#10:08 <+sawakita> exactly
|
|
#10:09 <+kanzure> what does a tile id reference
|
|
#10:10 <+sawakita> tile ID $00 is the first tile of the tileset's graphics (first 16-bytes, since gfx are 2bpp)
