API for loading:
|
|
|
|
+ Disk based:
|
|
returns to ????? with LOCATION (no extra action needed)
|
|
LEVEL
|
|
DISK
|
|
set
|
|
|
|
the code looks up track/sector/length based on these,
|
|
changing disk if necessary
|
|
|
|
+ Prodos/HD based
|
|
|
|
+ proboothd boots disk
|
|
+ loads QLOAD to 1600
|
|
|
|
|
|
DDDD DDDT | TTTT TSSS
|
|
|
|
((disk+1)<<9)+(T<<3)+(S>>1)
|
|
|
|
((disk*512) + (T*8) + (S/2)
|
|
|
|
256k for each 140k disk, offset from there?
|
|
up to 128 disks
|
|
|
|
|
|
only one copy of qload/title
|
|
|
|
if level/disk changes, convert to filename
|
|
DISK00/FILE00
|
|
and load it
|
|
|
|
|
|
REMEMBER! QLOAD actually trashes 2 bytes above the top of the load
|
|
for most of this we re-write those bytes and it doesn't matter
|
|
but it does mean we can't load right up against $C000 as that's
|
|
I/O memory and we'll get weird corruption issues.

could in theory load to $1000 instead when using HD

(old) map to 12 colors and eyeball which?
|
|
(old) contrast/bright 57/3 (note: not always or even often)
|
|
|
|
dark areas, crank shadow removal to 80?
|
|
|
|
on some hard to define areas crank contrast to 50?
|
|
|
|
on atrus movie go to color levels and hit "auto" before iipix
|
|
|
|
final movie roto procedure:
|
|
scale to 40x50
|
|
crop to 40x48
|
|
add layer
|
|
paste overlay mask on top
|
|
rotoscope
|
|
copy to new image
|
|
convert to indexed apple II palette
|
|
scale to 80x48
|
|
save

graphics notes:
|
|
in dark areas, use the shadow tool at 80 or so?
|
|
|
|
in bright areas, pumping contrast up to 30 - 40 can help?
