# penetrator
|
||||
Remake of the ZX Spectrum game for the Apple II.
|
||||
|
||||
1. INTRODUCTION
|
||||
|
||||
This is a "port" of the Commander X16 version that's also in my repo's as just
|
||||
penetrator. I had to rewrite quite a bit of the drawing code and make some
|
||||
other changes to make it work on the Apple II, and to make it fast enough.
|
||||
|
||||
This is also my very first program for the Apple II. It was a learning
|
||||
experience :)
|
||||
|
||||
2. CURRENT STATUS
|
||||
|
||||
The game is a pretty good replica of the original. It is missing the demo
|
||||
attract mode, and the fireworks.
|
||||
|
||||
Video https://youtu.be/fVms0nNVDtY and here's Oliver Schmidt's son, Pascal,
|
||||
playing the game on real hardware: https://www.youtube.com/watch?v=rXC2JKuN594
|
||||
|
||||
There's also a pre-built Apple II disk of the project, Penetrator.dsk under the
|
||||
releases tab. This can be played directly in emulators.
|
||||
|
||||
3. TECHNICAL DETAILS
|
||||
|
||||
The game is written in 6502 assembly using the ca65 assembler.
|
||||
|
||||
Below is a CPU cycle profile of 1 game frame in stage 4. It's a busy frame with
|
||||
bullets, bombs and enemies. Most importantly, it has a busy terrain at the top
|
||||
and bottom.

Remake of the ZX Spectrum game for the Apple II.
|
||||
|
||||
As can be seen, clearing the area where the world will be drawn takes almost 35%
|
||||
of the frame and drawing the terrain takes another 31% of the frame. The
|
||||
Emulator Error are unaccounted for cycles -discrepency between total cycles at
|
||||
the start and end, vs. the cycles reported in each step. I modifies the
|
||||
emulator myself to do step reporting and I assume I must have missed someting.
|
||||
|
||||
4. KEYS and JOYSTICK
|
||||
|
||||
The Apple 2 gameplay works only with a joystick since you cannot detect multiple
|
||||
keys down on the Apple II. The UI works with the keyboard or joystick and the
|
||||
world editor uses both.
|
||||
|
||||
The joystick can also drive the menu's. Pressing right, for example, is
|
||||
equivalent to pressing 1 (the UI menu options are selected through numbers).
|
||||
|
||||
The menus all show the keys to advance. There's also a help screen in the
|
||||
editor.
|
||||
|
||||
5. THE FILES
|
||||
|
||||
I tried to comment all the code very thoroughly in the CX16 version. Since this
|
||||
version is derived from that version, the code is also well documented, but to
|
||||
be honest, the comments may not always be accurate. I did not do a pass to see
|
||||
if they are accurate.
|
||||
|
||||
There are actually 2 programs in this. The 1st is the game, and it's in
|
||||
src/apple2.
|
||||
|
||||
* audio.inc - Routines to make the speaker beep
|
||||
* defs.inc - Constants and definitions used throughout
|
||||
* draw.inc - HGR buffer drawing. drawSprite, for example
|
||||
* edit.inc - The built-in world editor
|
||||
* file.inc - Load and Save code
|
||||
* fontdata.inc - A ZX Spectrum font in reverse 8x8 - Apple II format
|
||||
* game.inc - The in-game logic, AI etc. The bulk of the "game"
|
||||
* input.inc - User controls for game and editor
|
||||
* logo.hgr - 8Kb splash screen in HGR format
|
||||
* logo.inc - File that simply does an incbin on logo.hgr
|
||||
* logodata.inc - Line data for writing Penetrator and logo image data
|
||||
* macros.inc - Print macros mostly
|
||||
* penetrator.asm - Where the game starts, initial setup, etc.
|
||||
* penetrator.cfg - ca65 configuration file
|
||||
* rodata.inc - Read-only data such as lookup tables, sprites etc.
|
||||
* terrain.inc - The terrain drawing routines
|
||||
* text.inc - In game text and print functions
|
||||
* trndata.inc - The world data (triplet - top, bottom and enemy pos)
|
||||
* ui.inc - User facing screens, name input, etc.
|
||||
* variables.inc - All non zero page variables (stats, scores, draw buffers)
|
||||
* zpvars.inc - The zero page variables (most variables)
|
||||
|
||||
The second is the ProDos loader that will auto-load the game. It's in the
|
||||
src/apple2.loader folder. It has these files (all provided to me by Oliver
|
||||
Schmidt)
|
||||
|
||||
* loader.cfg - ca65 configuration file
|
||||
* loader.s - file to load and start the game
|
||||
|
||||
6. BUILDING THE GAME
|
||||
|
||||
Making the game has a few steps. Use make and the Makefile on all OSs, that
|
||||
would be the easiest.
|
||||
|
||||
Start by making the loader - this needs to be done once only.
|
||||
make TARGETS=apple2.loader
|
||||
|
||||
Next, make the game with:
|
||||
make
|
||||
|
||||
The next step is to make a bootable disk image. For this, you will need 3rd
|
||||
party software. I use AppleCommander. This software will put the loader and
|
||||
game into the disk image. You will need to install Java to use AppleCommander.
|
||||
|
||||
The apple2/template.dsk is a "blank ProDos floppy" that has the loader and the
|
||||
game placed on it by AppleCommander.
|
||||
|
||||
To make the disc image, set an environment variable to point at apple commander
|
||||
(see notes) and then use the command:
|
||||
make dsk
|
||||
|
||||
This will make a disc named Penetrator.dsk which can be loaded up in an
|
||||
emulator.
|
||||
|
||||
If you want to edit the code and get into some iterative development/testing,
|
||||
you can edit the Makefile and fill in the commands commands neccesary to launch
|
||||
an emulator as well. Look for apple2_EMUCMD and set that as neccesary. The
|
||||
simplest is to call test.sh or test.bat and fill in a complete command in the
|
||||
batch file or shell script. However you choose to do this, once done, you can
|
||||
do everything with the command:
|
||||
make dsk test
|
||||
|
||||
NOTES:
|
||||
1) Find AppleCommander here (I used Version 1.5.0):
|
||||
https://github.com/AppleCommander/AppleCommander/releases
|
||||
2) Set the environment variable (or change the Makefile-dsk.md) to point at the
|
||||
apple commander jar file. Here's how it's done for different shell's:
|
||||
Powershell:
|
||||
$env:AC = "path to apple commander.jar"
|
||||
cmd.exe
|
||||
set AC="path to apple commander.jar"
|
||||
bash (Unix or MacOS terminal):
|
||||
export AC="path to apple commander.jar"
|
||||
|
||||
7. CREDITS
|
||||
|
||||
* Phillip Mitchell and Beam Software for creating and publishing the game in
|
||||
1982.
|
||||
* A special call-out to Oliver Schmidt who provided me with invaluable
|
||||
assistance to get me going on the Apple II.
|
||||
* Everyone involved in the Apple II projects (AppleWin | AppleCommander).
|
||||
* Everyone involved in making the cc65 tools, it's very good.
