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
credits
c64:
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
