- Zeroth BADGE Killer Demo entry -- October, 1987

-
- This video, entitled "Amiga Does It Better", is from an
- alternate universe where not only does Commodore advertise
- the Amiga, but the Beatles are still together!
-
- To Run:
- You'll need more than 512K.
- Make sure all the data files are in the current directory. There's a
- list at the end of this README file.
- To start, type "Killer" from the CLI, or double-click the icon.
- If you don't have enough memory, or the proper data files are not
- present, you'll get a message like "initmusic error" or
- "initgfx error".
- Once video starts, click upper left corner if you wish to exit. (Sorry,
- as of the moment you can't bail out before then.)
- The video lasts exactly one minute. Ideal for television use!!

-
- Thanks to all who (unknowingly) contributed:
- The instruments are from some old Amiga music demo. Thanks to Bobby Deen
- for information on the file format. Thanks to whoever for the
- instruments.
- Thanks to Rob Peck for a working example of how to use the audio device.
- Special thanks to the artists whose pictures I usurped. They include
- RJA, (Opus), GJ (?) (Gorilla), Sullivan (Marilyn), HUD (lunar
- landscape), and to the unknowns who created the Bugs Bunny and
- Fractal Firestorm pictures.
- Thanks to the Beatles for music I never tire of.
- And finally, thanks to Commodore-Amiga for a way to express my
- creative (dis)ability.
-
-
- Technical Notes:
- The picture files are not IFF, but rather are bitmap structures followed
- by 5 planes of data.
- The instruments are not IFF either, they are from an old music demo
- that comes from I-don't-know-where.
- The screen is a 640x200x5 bitmap. It is displayed in 320x200 mode,
- so only half is visible at a time. This is very convenient for
- purposes of scrolling and double-buffered animation.
- Three tasks are used: a high-priority music task, a medium-priority
- graphics task, and a very-high-priority monitor task which looks for
- Close requests from the user.
- Timing is supplied by a vertical-blank interrupt routine. Both the
- graphics and music tasks have a list of "events" which describe what
- to do and when to do it. These tasks set an "alarm clock" for the
- next event, and then sleep until the vertical-blank routine wakes them
- up. The graphics task especially tends to get behind in places (i.e.
- slight jitter in scrolling of Yellow Submarine at start), and in
- that case just keeps doing things until it's caught up.
- The program was compiled with Lattice 3.03.
- Source will be out "sometime" (like, say, after my general exam).
