0.1 General
~~~~~~~~~~~
Offender is based on the classical game Defender® by Williams Corporation.
Offender was coded from the scratch and all game features have been
based on the memory of the author (spending too much time at the arcade
machines :-)).
0.2 Hardware requirements
~~~~~~~~~~~~~~~~~~~~~~~~~
Offender requires an Amiga with a 68020 CPU and a 68881 FPU or better.
It has been developed on an A3000 with 68030 CPU and 68882 FPU (25 MHz).
68040 users should know that Offender uses some trigonometric FPU instructions
not available on their CPU, but with the right F-line trap-handler this should
not be a problem.
¡¡¡ Important Note : Offender will definitely NOT run on an Amiga with a
68000 or 68010 CPU or without a FPU. I'm NOT planning to release a version
for those chips !!!
The demo version requires 446 kByte chip and 109 kByte fast memory. If
there's not enough chip memory available, you won't hear all sounds, but
the game is playable.
The full version will need 698 kByte of chip memory to load all sounds.
With fewer memory you won't hear all of them, either.
A standard joystick connected to port 2 is required.
0.3 Software requirements
~~~~~~~~~~~~~~~~~~~~~~~~~
Offender requires Kickstart 1.3 or 2.0.
It needs the standard diskfont.library in the LIBS: directory and the files
Script.font, Script/15 and Script/20 (included with Offender) in the FONTS:
directory.
0.4 Multitasking considerations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Offender uses all four sound channels. If it can't allocate them. it'll
exit. Improper operation can be caused by other programs not using the
proper sharing protocol.
Though Offender takes control over the keyboard and the mouse, other tasks
will continue to run. You just can't communicate with them. So you can do
a lengthy download or compiler run or whatelse while playing Offender.
You should ChangeTaskPri Offender to a higher priority than the other tasks
to gain snappy respondence. Offender doesn't Forbid() or Disable(), so
interrupt-driven background tasks (like downloading) aren't disturbed.
Offender uses CPU time proportional to the number of objects on the screen.
So, most of the time (when there're only a few objects) other tasks will get
enough CPU time. On the other hand, sometimes (but only for short periods, e.g.
when smartbombing a screenfull of aliens) Offender needs much more CPU
cycles, so you should run Offender at a higher task priority to avoid slowing
down the animations.

0.6 Installation
~~~~~~~~~~~~~~~~
Copy 'Script.font', 'Script/15', and 'Script/20' to your FONTS: directory
Copy all other files (including the 'PoorSounds' subdirectory) into any
directory you like.
0.7 Running Offender
~~~~~~~~~~~~~~~~~~~~
CD to the directory where Offender resides and type 'Offender_NTSC_demo' or
'Offender_PAL_demo' to start it. Or doubleclick the icon. Offender might
create the file 'Offender.HiScore' in the current directory, but you may
delete it to start again with a virgin hiscore table.
0.8 Differences between PAL and NTSC versions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The PAL version uses the extra lines available and plays at 50 frames per
second; the NTSC version plays at 60 frames per second but is restricted
to 200 horizontal lines. Because of the higher frame rate the NTSC version
requires more CPU power, so you should use the PAL version if you have a
slow CPU. Though timing is based on the frame rate, the overall speed of
the game is the same in both versions.
0.9 Testing configurations
~~~~~~~~~~~~~~~~~~~~~~~~~~
Offender was tested and ran successfully on the following systems:
- A3000, 25MHz 68030 & 68882, 2 MB Chip, 12 MB Fast,
52 MB + 240 MB Quantum HDs, KS 37.175, WB 37.67
(my machine)
- A3000, 16MHz 68030 & 68882, 1 MB Chip, 1 MB Fast, 52 MB Quantum HD,
KS 36.143, WB 36.68
(Thanks to Pernhard!)
- A2000B with GVP turbo-board, 28MHz 68030, 33MHz 68882,
Kickstart 1.3
(Thanks to Pille!)
0.10 Bug reports
~~~~~~~~~~~~~~~~
Offender has been tested many hours and has been found 'bugfree' :-)
It'll exit if there's a resource not available giving you a short
explanation. If you should encounter an "Internal error RC = xxx" or
a guru or other strange behaviour, PLEASE report it to me together with
your system configuaration, including model, CPU type, FPU type, memory
configuration, Kickstart version etc.
0.11 Differences to the registered versions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This demo contains only the first 2 levels. Additionally all sound
effects are down-sampled to about 4000 samples per second.
The full registered version will contain all levels plus the original
sound effects at about 10000 samples per second. (450 kBytes sounds!)
The source code version will further include all sources in C and
assembler (SAS C 5.10 and SAS Assembler) as well as the IFF images
and the self-written tools used in developing Offender, together with
a documentation on the source code (in fact all the files on my hard disk
concerning Offender !).

0.12 Changes in version 1.01
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Offender is now safer in low memory conditions. It will now leave at least
20 kByte of chip memory available possibly immolating some sound effects.
You may now delete or trash any sample file (even the whole PoorSounds
subdirectory) and Offender will run properly (without that sound of course)
When the volume containing FONTS: wasn't mounted during loading Offender,
it aborted without bringing up the requester "Please insert ...". This is
now fixed.
Offender has now been tested with Kickstart 2.04 (37.175) on my A3000 and ---
it works !
0.13 Changes in version 1.02
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A bug has been fixed, which made Offender crash on certain configurations
(an uninitialized pointer trashing random memory locations -- in fact
it was a miracle that this bug didn't do harm to my machine !!!)
[Several people reported this bug to me; thanks to all of them !]
A short delay has been added after shooting
