# Transition effects for SHR slideshows
|
|
#
|
|
# Each Mega-Attract Module that is an SHR slideshow (see ATTRACT.CONF)
|
|
# will use a single transition effect for the length of the module.
|
|
# Transition effects are loaded in the order listed in this file. Each line
|
|
# of this file is a filename (not including comments, like this one). The
|
|
# name of the next transition effect is stored in the global prefs, so this
|
|
# file should not contain duplicates.
|
|
#
|
|
# Transition effects are binary files loaded at $A000 and called with main
|
|
# memory banked in (read/write) and the next SHR graphic already loaded at
|
|
# $2000/main. A transition effect has full use of zero page (main),
|
|
# $0200-$07FF (main), and $A000-$BEFF/main. $BF00-$BFFF/main is reserved for
|
|
# the ProDOS shim. LC RAM banks 1 and 2 are reserved for the launcher.
|
|
#
|
|
# /!\ You can not assume auxiliary memory exists! No, really.
|
|
#
|
|
# Consider this (supported) configuration: Apple ][+, 64K, VidHD card.
|
|
# This machine is capable of displaying SHR graphics by copying pixel and
|
|
# palette data from $2000-$9FFF/main to $2000-$9FFF/aux, despite the fact
|
|
# that auxiliary memory does not exist and the writes will actually go to
|
|
# main memory. However, the VidHD card notices and respects the WRITEAUXMEM
|
|
# softswitch and will cache the data in its internal cache and ultimately
|
|
# display it.
|
|
#
|
|
# Even worse, this means that SHR transitions must be careful about writing
|
|
# to aux anything other than the current value of that address in main,
|
|
# because in some (supported) configurations, those writes will actually
|
|
# be altering main memory. Example: you want to clear the palettes space
|
|
# before progressively fading them in. Writing all zeros to the palettes
|
|
# in "auxiliary" memory will actually overwrite the original palettes in
|
|
# main memory.
|
|
#
|
|
# Important: LC RAM bank 1 will be read/write on entry and must be read/write
|
|
# on exit. If you need ROM routines, you are responsible for switching to ROM
|
|
# then switching back to RAM bank 1 (read/write) before returning. However,
|
|
# you can leave WRITEAUXMEM active; the calling code unconditionally switches
|
|
# back to WRITEMAINMEM after the transition code returns.
|
|
#
|
|
# This file is converted to a binary data structure (SFX.IDX) during build
|
|
# then added to TOTAL.DATA on the final disk image.
