# transition effects for HGR slideshows
#
# Each Mega-Attract Module that is an HGR 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 $6000 and called with
# hi-res page 1 showing and the next HGR graphic already loaded at $4000.
# A transition effect has full use of main memory, including zero page and
# text page if needed. LC RAM banks 1 and 2 are reserved for the launcher.
#
# 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.
