256-byte Intro for Apple II, Outline 2022
by Deater / dSr
Wiggles the Desire logo in Hires (shape tables and page flip)
Then scrolls some lo-res chunky pixels under a DSR logo.
The lo-res pattern is just ROM/RAM contents, so some of it
might look a bit different depending on the state of RAM.
It plays some sound through the beeper/speaker. No timers
on the Apple II so that's all cycle counted.
There are various tricks going on to make this all fit.
