BlueFlame, 1k Apple II Hi-res demo presented at Lovebyte 2023

Code by Deater

Music by MA2E
|

ZX02 compression by DMSC

|
1k entries are difficult as it's so much bitter than 256 bytes so you
|
|
feel like you should be able to do a lot, but at the same time it's
|
|
a lot more work for not much better production.
|
|
|
|
The shape-table letter motions were the first idea and turned out well.
|
|
It's convenient DEATER and DESIRE share so many letters. Also thought
|
|
maybe A DEMO or DEMO OVER could be printed but that ended up not being
|
|
necessary.
|
|
|
|
The "blue flame" is essentially my attempt at the Doom Fire for hi-res.
|
|
It's actually doing the effect on PAGE2 and copying to PAGE1 each frame.
|
|
|
|
The "static column" effect was a 32-byte effect I had come up with a while
|
|
ago.
|
|
|
|
The parallax-sierpinski at the beginning was an attempt to do some sort
|
|
of hi-res parallax effect on the Apple II. Scrolling hi-res is slow at
|
|
the best of times so I was using sierpinski (and) and boxes (xor) to
|
|
make things simpler, and even then the framerate isn't that great.
|
|
|
|
The music is by MA2E and uses a simple 2-track music tracker I have.
|
|
|
|
This was compressed with ZX02 compression. The small ZX02 decompressor
|
|
is around 130 bytes of code, but the music especially compressed more than
|
|
this so it was a win. It did make size-optimizing difficult as optimizing
|
|
for compression is dificult. Shaving bytes off the uncompressed code can
|
|
actually make the compressed image bigger.
