Is it possible to get 40x96 as well as HGR?
|
||||||
|
|
||||||
|
Have same HGR background page0/page1
|
||||||
|
Alternate PAGE0/PAGE1 every two lines... do this in SPLIT?
|
||||||
|
|

|
Is it even possible to draw the lines/sprites fast enough in the
|

|
space remaining?
|

|
|
||||||
|
Only draw the top half on odd frames, bottom on even?
