"Lion" by Manwe/SandS
4kb procedural graphics
for BK 0010 & BK 0011
Released at DiHalt 2022
10 colors on 4-color computer? Easy!
Thanks to screen page flickering (so
called double-screen)... But wait a
minute! BK 0010 has no video pages!
So how is it possible and what does
this program actually demonstrate?
First of all, it's not just a picture,
since dithering is software generated
- the only way to fit into 4 kb limit.
Secondly, the program moves video data
"manually", word by word, every frame,
on the top possible speed. That's why
only 1/4 of the screen is displayed.
Bandwidth limit is reached.
You can hit a key to fix the frame
tearing. Try until success.
