some questions regarding the "star trek 25th anniversary AGA"-problem.
is it a hd installed game or a disk-based game?
does it use some custom screenmode-settings or custom overscan-settings?
the different way of indivision work is the "identification" of a screenmode.
it tries to detect a "known" mode for best output frequencies.
the latest flash supports the HD720 mode with 1280x720
first AGA 16:9-screenmode :-)
