Trionoids is a Columns clone for the Atari Falcon030. It may be ported to the
ST, right now it's using the Falcon's true colour mode so a lot of the graphics
routines and assets would have to be changed for that to happen.
The game requires VGA at 60Hz.
How To Play
Trionoids drop down the screen in groups of three, you can switch their order
by pressing up or down to 'rotate' in the associated direction and move the
column of three left and right. Match 3 or more either horizontally, vertically
or diagonally for the good stuff (points). Pressing fire drops the Trionoids
faster. The game speeds up over time, so for the best score you need to drop
Action | Joystick | Keyboard
Rotate up | Up | Up Cursor
Rotate down | Down | Down Cursor
Move left | Left | Left Cursor
Move right | Right | Right Cursor
Drop | Fire | Spacebar
Known bugs (as of 1.0)
* Sound effects don't always work on real hardware. That said, they don't sound
as good as the music anyway.
Do whatever you want with the game or the source (see below), but don't sell
Massive thanks to the [Dead Hackers Society](www.dhs.nu) for their DHS Falcon
Demosystem which is used to set the screen modes and a whole lot more, and to
Nyh! for his joystick code. Thanks to Laurent S (Thados) for helping get
me started in a number of areas. Finally a massive thank you to dml who taught
me a hell of a lot with technical advice and examples.

This is my first major assembly project so there's plenty of code that's
nowhere near optimised, and even more that's absolutely horrible in terms of
design. I've learned a lot over the last few months, especially about how hard
refactoring assembly code is ;)
This code should assemble without issue in Devpac 3.1.
