WORDS FROM THE AUTHOR
There weren't many issues to fix with the game. The disk uses a dual format
to support running on both Atari ST and Amiga. The ST version is on side 0,
while the Amiga loads from side 1 but borrows the graphics from the ST side.
This leaves lots of extra space for the Amiga to add exclusive sound effects
and music, thus taking advantage of the superior Paula chip.
The save system originally used an entire floppy just to store one snapshot!
I've reworked this, as it was easy to extend it to support multiple saves.
During the game, press L to load or S to save, and you'll be shown a list of
slots to choose from. Amusingly, entering these menus always resets the
enemies on screen, even if you press Escape to cancel!
Besides that, there were some stray accesses to the Atari TOS ROM still in
the Amiga version, and the interrupts didn't work correctly with WHDLoad due
to expecting a0 to always stay set to $dff000. Plus the usual suspects like
CPU-dependent timing and missing blitter waits.
Greetings and thanks to Chris for the original disk, to the folks at the EAB
forum for help investigating the disk image, and to the contributor who
wishes to remain anonymous for supplying hints and testing the game!
Enjoy! :-)
