256-byte Intro for Apple II, Outline 2024
|
||||
by Deater / dSr
|
||||
|
||||
If you zoom in on the bubble universe
|
||||
you may find cosmic fish.
|
||||
|
||||
Apple II 'lo-res' 40x48 15 color mode
|
||||
|
||||
Core routine based on serato_fig's
|
||||
C64 version
|
||||
|
||||
A lot of the fun was generating
|
||||
256-entry sine and cosine tables
|
||||
|
||||
Also a 256 entry color-fade table
|
||||
(complicated as two pixels are in the
|
||||
top/bottom of a byte and they fade
|
||||
independently)
|
||||
|
||||
There is sound but admittedly it
|
||||
isn't the best.

IT CAUSED A MAJOR POLITICAL UPHEVAL.

WERE FREE FROM ENSLAVEMENT, AND THE

GARGS (THE VICIOUS, AGGRESSIVE

THE MARTIANS CREATED ROBOTS FOR MENIAL

WORK AND GUARD DUTIES. BEWARE OF THE

TANK-LIKE GUARD ROBOTS--THEY ARE VERY
