Bubble Blob
|

-
|
||||
256-byte Intro for Apple II, Outline 2024
|
||||
by Deater / dSr
|
||||
|
||||
Bubble universe has two paramaters, I and J.
|
||||
If you set I to 1 you get a much more restrained
|
||||
set of shapes.
|
||||
|
||||
Apple II 'hi-res' 280x192 6 color mode
|
||||
|
||||
Core routine based on serato_fig's
|
||||
C64 version
|
||||
|
||||
Using ROM routines for plot (which are slow).
|
||||
ROM clear-screen routing way too slow so
|
||||
spending some bytes on a moderately fast
|
||||
clear screen.
|
||||
|
||||
I was hoping to get this down to 128 bytes but
|
||||
can't seem to get it below 200 bytes, so added
|
||||
in some extra effects.
|
||||
|
||||
There is sound but admittedly it
|
||||
isn't the best.
