Copyright/License

z26 is Copyright ©1997-2019 by John Saeger and contributors. z26 is released subject to the terms and conditions of the GNU General Public License Version 2 (GPL). z26 comes with no warranty. Please see the included COPYING.TXT for details. Source code for the current release is available at the home page listed above.

What's new in version 4.06?

Software Requirements

This version of z26 is known to work on Windows 10, Linux, and Intel Macintoshes. As this version of z26 is written in C, it is possible to compile and run this version of z26 on 64-bit Linux systems as well as the Raspberry Pi, but your system needs to support OpenGL.

Hardware Requirements

A computer with reasonably fast processors, hardware support for OpenGL, and a working vsync. A Raspberry Pi version 1 or a Raspberry Pi Zero should be fast enough.

Windows Installation

Unzip the z26 archive. You can leave it in the download directory if you want. You will need a copy of SDL2.dll either in the z26 directory, or in the Windows directory. This .dll is included in the .zip file along with the z26 executable. If you like you can pin z26 to the taskbar. Then you can click to run it.

Macintosh Installation

Unzip the archive. You can leave the folder in the download directory if you want. Or you can move the app to the applications folder. Then if you like, just drag the app to the dock. Click to run.

Linux Installation

First, you need the build tools and the SDL 2.0 library. On a debian based system open a terminal and type:

     sudo apt-get install build-essential
     sudo apt-get install libsdl2-dev

Otherwise use the method from your distro to install these packages. Don’t worry if build-essential is already installed. It is becoming more common for that package to be installed out of the box. Unzip the z26 source archive, open a terminal in the resulting source directory and type:

     make linux

If all goes well, when it's done you'll have an executable named z26 that you can put where you like. To run z26, open a terminal in the directory you put z26 and type ./z26 at the command line prompt. This should make z26 available in your menu system and can be run from there for future uses. You should also be able to put a launcher on the desktop or in an application launcher like other linux desktop apps.

Setting up the Raspberry Pi

First, we want to make sure your system is up to date. Open a terminal and type:

     sudo apt-get update
     sudo apt-get dist-upgrade

Reboot your system. Then install the dependencies. You need the build tools and the SDL 2.0 development library.

     sudo apt-get install build-essential
     sudo apt-get install libsdl2-dev

Don’t worry if build-essential is already installed. It is becoming more common for that package to be installed out of the box. Unzip the z26 source archive, open a terminal in the resulting source directory and type:

     make linux

If all goes well, when it's done you'll have an executable named z26 that you can put where you like. Before running z26, you need to enable the OpenGL drivers by running:

     sudo raspi-config

Choose option 7 – Advanced Options.
Then choose option A7 – GL Driver.
Then choose option G1 – GL (Full KMS).
Exit the config program by pressing escape until you reach the command line prompt and reboot your system.

To run z26, open a terminal in the directory you put z26 and type ./z26 at the command line prompt. This should make z26 available in your menu system and can be run from there for future uses. You should also be able to put a launcher on the desktop or in an application launcher or panel like other linux desktop apps.

Main Menu

After launching z26, you will be presented with the Main Menu. The current selection is highlighted. You can navigate the list with the vertical arrow keys, and you can make a selection by pressing the <enter> key or the <right arrow> key.

Video Menu

By default z26 runs full-screen at the resolution of your desktop since OpenGL vsync usually works best when run full-screen. A windowed display is provided, but it's not guaranteed to give smooth gaming performance.

Note that syncing the game to vsync is the only method provided for controlling game speed. Normally this is not a problem since OpenGL does a great job providing this feature and normally the refresh rate of the monitor is 60 Hz automatically. This is the correct speed for NTSC games which most Atari 2600 ROM images are. If however you are a serious gamer and you have a high performance monitor and like to set it to a higher frame rate like 100 Hz, 120 Hz or even 144 Hz, you will need to manually adjust the refresh rate of your monitor to 60 Hz to get correct game speed on NTSC games. PAL and SECAM games are best run at 50 Hz. My main Linux system supports changing the monitor refresh rate to 50 Hz which is pretty nice. I can play PAL games at the proper speed. But this feature is not necessarily supported on your platform and so far I’ve not found it on the Raspberry Pi. So your mileage may vary and frankly, running PAL games at 60 Hz is not such a terrible thing to do.

A number of textures are provided to give control over game detail and sharpness. Width is continuously variable and the scanline effect has variable depth. So you can control the display much as you might control the display on a real 2600 connected to an old-school TV set. Scanline display requires normal or HD textures to be enabled. HD gives the best scanlines but also requires the most CPU resources. If you choose a fast texture you get a simplified video menu:

Video Options

         Display........: Full Screen    Full Screen or Window.
         Texture........: Fast Sharp     Fast, normal, and HD – blurry or sharp.
         Width..........: 100            Continuously variable.
         Vsync..........: Yes            Turn Vsync on or off.

         Exit                            Return to Main Menu.

If you have selected a normal or HD texture you get an expanded menu with the ability to set scanline options:

Video Options

         Display........: Full Screen    Full Screen or Window.
         Texture........: Normal Sharp   Fast, normal, and HD – blurry or sharp.
         Width..........: 100            Continuously variable.
         Line Mode......: Normal         Normal or Scanline.
         Scanline Depth.: 60             Continuously variable.
         Vsync..........: Yes            Turn Vsync on or off.

         Exit                            Return to Main Menu.

Sound Menu

You can turn the sound on and off with this menu.

Sound Options

         Exit                        Return to Main Menu.

Interface Menu

Here you can tune the user inputs to the game. You can also choose to turn on the scanline and framerate display, as well as set the GUI color scheme.

Interface Options

Restoring Defaults

Delete the file z26.gui from the startup directory.

Console Controls

To control the switches on the main console box, use the function keys on the keyboard as follows:

   F1 -- Reset
   F2 -- Select
   F3 -- B/W
   F4 -- Color
   F5 -- Player 0 easy
   F6 -- Player 0 hard
   F7 -- Player 1 easy
   F8 -- Player 1 hard

Paddles

z26 supports the use of the mouse or PC trackball to play paddle games. If you want to change which paddle is emulated with the mouse use the Controller Tweaks Menu. You can change which direction the mouse must be moved in to get paddle motion by pressing the <Tab> key on the keyboard while you're playing a game. You can emulate two paddles with a mouse with one paddle on each axis. You can use the keyboard to play paddle games. If z26 doesn't automatically support a game as a paddle game you may specify which controllers are paddle controllers in the Game Options menu.

Paddles may be controlled from the keyboard as follows:

  Ctrl -- fire paddle 0 Use left and right arrows to move
RShift -- fire paddle 1 Use up and down arrows to move
     n -- fire paddle 2 Use 's' and 'f' to move
     v -- fire paddle 3 Use 'e' and 'd' to move

Joystick

PC or USB joysticks and gamepads are supported to the extent that the operating system and SDL supports them for playing joystick games. The mouse and PC keyboard may also be used. Some games like raiders.bin use the "wrong" joystick. To reverse the joysticks, reverse the ports under the Game Options Menu. Joysticks may be controlled from the keyboard as follows:

Player 0

  Ctrl -- fire  Use the arrow keys to move.
     / -- trigger (booster grip)
RShift -- booster (booster grip)

Player 1

    n -- fire
    s -- left
    e -- up
    f -- right
    d -- down
    b -- trigger (booster grip)
    v -- booster (booster grip)

Driving Controller

z26 suppports the game that uses the driving controller (Indy 500) from the keyboard as follows:

Player 0

       Ctrl -- accelerate
right arrow -- turn clockwise
 left arrow -- turn counter-clockwise

Player 1

          n -- accelerate
          f -- turn clockwise
          s -- turn counter-clockwise

Keyboard Controllers

       Left Port                     Right Port
7 -- 1   8 -- 2   9 -- 3      1 -- 1   2 -- 2   3 -- 3
u -- 4   i -- 5   o -- 6      q -- 4   w -- 5   e -- 6

Compumate Keyboard

Use PC keyboard columns 1 - 0

  Ctrl -- FUNC
LShift – SHIFT

Mindlink Controller

Use the mouse to move horizontally.

button -- start the game
   Tab -- switch between player 0 and player 1

Mouse Handling in Paddle emulation

   Tab -- switch between horiz. normal, vert. normal
          and horiz. reversed, and vert reversed

Kid Vid Controller

Use keys 1 2 3 to start the corresponding tape.

F1 stops and rewinds the tape.

Trak-Ball Controllers

Atari sold a Trak-Ball that could be used to play joystick games. z26 supports the use of a mouse or PC trakball to do the same thing for joystick games. Optical trackballs like the Logitech Marble Mouse are great for this. Also z26 emulates the various types of Atari Trak-Balls in their native modes.

Light Gun

z26 supports light gun games (Sentinel, Shooting Gallery) with the mouse.

Keyboard Controllers

z26 enables the keyboard/touch pad/keypad for recognized games that use them.

Booster Grip

z26 supports the booster grip game (Omega Race) from the keyboard and the PC joystick with 3 or more buttons.

Scrolling the Screen

If you don’t like how we’ve positioned the game on the screen you can move it around. These days the relevant keys are the versions of the keys that are not on the ten key pad. I guess you call them the keys on the “nav-cluster.”

 PgUp -- Scroll the screen up.
 PgDn -- Scroll the screen down.
 Home -- Return to the default screen position.

Trace Mode

You can start trace mode by launching z26 from the command line with the -t command line switch, or by enabling it in the Debug menu. It automatically builds a text file called z26.log in your home directory. This file is a log of all instructions executed and shows some other interesting things like the (frame number, scanline number, cpu cycle, tia clock), object positions (P0, P1, M0, M1, BL), cpu flags, registers (A, X, Y, SP), the program counter, the current instruction in hex, and a disassembled listing of the instruction.

Emulator performance slows down quite a bit while writing out this file so you can turn off writing with F12 and turn it back on with F11 to make it easier to get to the part of the game that you're interested in.

Counting Scan Lines and Showing FPS

By enabling the Show FPS option in the Interface Options menu, thee number of scan lines that a game is using as well as its play speed in frames per second (FPS) to be displayed. This is useful for testing PAL games so you can avoid the PAL color loss bug. Of course you can also enable the color loss by turning on the Colour Loss option in the Video Options menu. The display may be toggled with the <Alt-D> key combination.

Inactivating PC controller support

Some Atari controllers are simulated with more than one PC controller. If you are experiencing problems with this, you can disable one or more PC controllers for these Atari controller simulations. For example you might want to disable the PC mouse when you use the keyboard to play an Atari-joystick game, so that accidently pushing the mouse doesn't cause any unwanted movement. Also you might want to disable the PC joystick for paddle games, because the PC joystick always overrides all other PC controllers in the paddle simulation when one is plugged into the PC. Please look at the following table to find out which Atari controllers are simulated with which PC controller.

Atari/PC          keyboard  mouse  joystick
-------------------------------------------
joystick     JS      x        x       x
paddle       PC      x        x       x
keypad       KP      x        -       -
driving      DC      x        x       x
lightgun     LG      -        x       -
Compumate    CM      x        -       -
Kid Vid      KV      x        -       -
Mindlink     ML      -        x       -
ST mouse     ST      -        x       -
Trak-Ball    TB      -        x       -
Amiga mouse  AM      -        x       -

Please note that inactivating the PC controller only works for Atari controllers that are simulated by more than one PC controller.

Colors (palettes)

z26 supports three different sets of colors or palettes. The most common games shipped in North America use the so called NTSC colors. Games shipped in other parts of the world use the so called PAL colors. z26 typically detects the correct colors, but you can override the colors chosen by z26 with the Palette option in the Game Options menu.

z26 also supports the bug in PAL consoles that causes the display to display a monochrome image if a game has the wrong number of scanlines. This feature is enabled with the Colour Loss option in the Video Options menu. Some of the 32-in-1 games which were poorly done PAL hacks show this effect.

SECAM colors can be selected with Palette option in the Game Menu. In the time before the crash Atari created most of it's PAL games in such a way that the B/W switch would enable SECAM compatible colors. So nostalgic gamers from France can play PAL ROMs by selecting this option.

Forcing Black and White mode

You can force a game to start in black and white mode with the Console B/W option in the Game Options menu. Note that this doesn't mean that the game will actually be in black and white, this merely sets the console B/W switch which the game may or may not ignore.

Starpath Games

For most Starpath games, the .bin file must be a multiple of 8448 bytes big. To run multiload games you must concatenate the .bin files. Under Windows, a command like this will do the trick:

     copy /b load1.bin+load2.bin+load3.bin+load4.bin mload.bin

Under Linux something like this will work:

     cat load1.bin load2.bin load3.bin load4.bin > mload.bin

Then run mload.bin in the emulator. z26 supports a maximum of 61 loads.

z26 also supports the 6144 byte Starpath format.

The Extended Tigervision (#11) bankswitch scheme allows ROMs up to 512K in size keeping the last bank fixed. All ROM images that are bigger than 64K and not a multiple of 8448 default to this scheme.

The original Tigervision (#4) bankswitch scheme also supports up to 512K games but with $1800-$1FFF as the fixed bank. This allows compatibility with the Cuttle Cart for games up to 64K in size.

Kid Vid Tapes

z26 supports the Kid Vid games (Smurfs Save the Day and Berenstain Bears) automatically.

Press 1, 2, or 3 to select the corresponding tape. F1 rewinds the tape. In addition to the rom images, you need the wave files with the music in the same directory as z26.

The files may be found at http://www.atariage.com/2600/archives/KidVidAudio/. They are named:

Berenstain Bears:

KVB1.WAV, KVB2.WAV, KVB3.WAV

Smurfs Save the Day:

KVS1.WAV, KVS2.WAV, KVS3.WAV

Both:

KVSHARED.WAV

You can also play the games without the music, but it's much less fun.

Command-line Switches

For information on how the command line switches work, please see the source file cli.c.

Troubleshooting

z26 runs too fast.

It’s possible that your hardware vsync isn’t working but it’s more likely that you’ve set the refresh rate of your monitor too high. Try setting the refresh rate to 60 Hz for NTSC games or to 50 Hz for PAL or SECAM games.

z26 runs too slowly.

Try a faster texture. HD textures are very demanding.

z26 sounds bad.

Turn off the sound in the Sound Menu.

And thanks to Len Shikowitz for *complaining* well beyond the call of duty. Definitely "the most obstinate, yet sincere, tester." :)

At some point I stopped keeping the list of everyone who have sent me suggestions up to date. I apologize for that. But thanks to the folks who have continued to send in suggestions, even though they didn't make the list.

Thanks!!!
