- scroll logos in from right, then out to left

|
|
- scroll the text in
|

|
|
|
- smoother scrolling. Only need to scroll middle 20 bytes or so?
|
|
|
|
|
wait on vblank?

music:
|
|
|
|
|
good ay-3-8910 track from ZX, though missing the rumble of
|
|
|
|
|
opening credits. Full thing annoyingly just above 8k
|
|
|
|
|
(x compressed) though I've been sticking it in the language card
|
|
|
|
|
(16k expansion)
|
|
|
|
|
|
|
|
|
|
opening space scroll/credits
|
|
|
|
|
theoretically possible though horizontal scrolling on an Apple II
|
|
|
|
|
is next to impossible to do smoothly.
|
|
|
|
|
the spaceships can be done with hires software sprites
|
|
|
|
|
explosion?
|
|
|
|
|
title card
|
|
|
|
|
I think the ii-pix version turned out really nice
|
|
|
|
|
though as always highly dithered stuff like this
|
|
|
|
|
doesn't compress well (8k down to ?)
|
|
|
|
|
chess board transition
|
|
|
|
|
probably possible?
|
|
|
|
|
transparent polyhedron bouncing
|
|
|
|
|
no idea
|
|
|
|
|
dot tunnel
|
|
|
|
|
something similar probably possible
|
|
|
|
|
moire circles
|
|
|
|
|
probably not at that framerate
|
|
|
|
|
falling block transition
|
|
|
|
|
yes
|
|
|
|
|
moire lines
|
|
|
|
|
probably not
|
|
|
|
|
gorilla looking guy
|
|
|
|
|
decent dithered version. horizontal slide transition
|
|
|
|
|
is harder
|
|
|
|
|
fading tv transition
|
|
|
|
|
yes possible
|
|
|
|
|
leaves with message
|
|
|
|
|
leaves look OK. mapping text...?
|
|
|
|
|
head
|
|
|
|
|
ok in lo-res
|
|
|
|
|
bouncing sphere/lens
|
|
|
|
|
something can probably be approximated
|
|
|
|
|
rotozoom
|
|
|
|
|
do have rotozoom code but currently wrapping not implemented,
|
|
|
|
|
that really needs to be a power of 2 not 40x48 as current lores
|
|
|
|
|
pre-existing fine tune code with complicated fixed point multiply
|
|
|
|
|
plasma
|
|
|
|
|
never have had much luck with good plasma effect on Apple II
|
|
|
|
|
plasma cube
|
|
|
|
|
ha
|
|
|
|
|
bouncing dot string
|
|
|
|
|
hmmmm
|
|
|
|
|
trnasmission
|
|
|
|
|
should try art. weird pixelated sprite might be possible
|
|
|
|
|
3d plasma
|
|
|
|
|
urgh
|
|
|
|
|
polar bear
|
|
|
|
|
OK graphics, vertical bounce effect might be harder
|
|
|
|
|
3d town
|
|
|
|
|
blah
|
|
|
|
|
nuts picture
|
|
|
|
|
probably possible

|
|
|
|
intro, scrolling OK
|
|
|
|
|
they actually managed bouncing polyhedron
|
|
|
|
|
they did the particle tunnel
|
|
|
|
|
|
|
|
|
|
limited sort of circles, I prob have code that does that
|
|
|
|
|
|
|
|
|
|
tree, they manage the message
|
|
|
|
|
|
|
|
|
|
lens, rotozoom, plasma
|
|
|
|
|
|
|
|
|
|
even manage the spinning cube
|
|
|
|
|
|
|
|
|
|
and the string
|
|
|
|
|
|
|
|
|
|
their transmission, the sword is black and white
|
|
|
|
|
|
|
|
|
|
3d plasma is less impressive
|
|
|
|
|
|
|
|
|
|
bouncing polar bear black+white
|
|
|
|
|
|
|
|
|
|
3d is more limited/black white
|
