   At this time, your linux share name must contain the "/" character somewhere
   if you want it to be recognized as a linux share.
   For example :

   rlxshare=/home/player/roms@192.168.1.30:1400

 - Possible Samba fix/improvement : see next item

 - New network configuration parameters : XBox IP, Subnet Mask, Gateway IP.
   Access these through the Configuration -> Network Options menu or change
   them in the INI file :

   [GENERAL]
   LOCAL_IP=192.168.1.30
   SUBNET_MASK=255.255.255.0
   GATEWAY_IP=192.168.1.254
   
   LOCAL_IP is the XBox IP address
   SUBNET_MASK is the subnet mask 
   GATEWAY_IP is your default gateway

   Set these to the same values you use in your XBMP configuration file.
 
   This might help people with Samba issues.

   E:\SAVES\Z26X you can change it via the Z26X.INI file

 - Take in-game screenshots and display them on the game selection list

 - New UI feature - auto-screenshot capture mode.  When enabled, the emu
   will start taking screenshots at a user-defined interval.  Useful for
   ripping sprites/animation.

 - Graphics filters :

 - Every single in-game command is fully customizable on any of the
   four joypad controllers.

 - Map any emulator or UI command to a single button or a combination of
   two buttons.  (e.g. RTrigger+LTrigger = Save State)

 - Autofire capabilities for any emulator button on any controller

 - One-button combos (define a series of emulator commands to be played
   back when you press a user-definable XBox controller combination.)
   (E.g. Press RTrigger+LTrigger to execute the command string
   A,B,A,B,Up,Down,Left,Right)

 - Traverse any directory on any drive ( Continue selecting the parent
   directory entry on the file selection list to get the drive selection
   list.  Selectable drives are C, D, E, F, R, X, Y, Z, and SMB. 
   R is the CDROM drive.  SMB is the samba share you have defined in your
   Z26X.ini file.)  Press Y from any file-listing screen to go up one
   directory level.

 - All UI commands (save state, load state, screenshot, etc) can be
   invoked from the Options/Pause menu as well as in-game via your
   customized joypad mappings.

 - Can be invoked from a command-line to directly run a game from a front-end
   or dashboard and bypass the user-selection screens. (Only if the frontend
   or dashboard supports this feature.)

 - Can return to the launching program *if* the launching program supports this
   feature.  For example, if the custom-launch routines are incorporated into 
   a new frontend, that frontend could launch Z26X and when you exit 
   Z26X, that frontend can be automatically reloaded.  



Various Important Notes:


Default ROM dir is D:\A26ROMS


=====================
Relax Network Sharing
=====================

The relax sharing setting goes in the [GENERAL] section as follows:

rlxshare=c:\a26roms@192.168.123.77:8989

Replace 192.168.123.77 with your computer IP address and replace 8989 with the
port where you have Relax running.


============================
Note on Samba/NetBIOS Shares
============================

There are two INI file settings relating to Samba/NetBIOS sharing and they both
reside in the [GENERAL] section of Z26X.INI:

smbshare=smb://username:password@workgroup:ip_address/computername/sharename
smb_nameserver=192.168.0.1


The smbshare parameter accepts many different formats.  Here are the most 
common:

smbshare=smb://username:password@workgroup/computername/sharename
smbshare=smb://username:password@workgroup:ip_address/computername/sharename
smbshare=smb://username:password@computername/sharename
smbshare=smb://username:password@computername:ip_address/sharename
smbshare=smb://workgroup/computername/sharename
smbshare=smb://workgroup:ip_address/computername/sharename
smbshare=smb://computername/sharename
smbshare=smb://computername:ip_address/sharename

Please try all of the above combinations before deciding it does not work.
Also be aware that some people have to select their SMB drive in Z26X a few
times before any files appear.

If it's still not working, then set the nameserver equal to the IP address of
the computer you are trying to reach or set it equal to your NetBIOS name server.
(If you don't know what a NetBIOS name server is, then just set it to the 
IP address of the computer you are trying to reach.)


Also remember that when you make changes to Z26X.INI, you have to do a 
"Force Reload of D:\*.INI" from the Configuration Menu or else the changes
you made to Z26X.INI will not be loaded.  




=============
Configuration
=============

Almost everything can be changed from the configuration menu.  Here are the
things that require manual modifications to the Z26X.INI file included in
the package:

Samba share name - goes in the [GENERAL] section.  Example:

smbshare=SMB://USERNAME:PASSWORD@COMPUTERNAME/SHARENAME


Screenshot directory - default is E:\SCREENSHOTS - goes in [GENERAL] section
Example:

screenshot_dir=E:\SCREENSHOTS


Skin directory - where skins can be found.  Default is D:\EMUSKINS - goes in
[GENERAL] section.  Example:

skin_dir=D:\EMUSKINS


Save directory - this is where you want all your saved games to be stored.
Default is E:\SAVES\Z26X.  Goes in [GENERAL] section.  Example:

save_dir=E:\SAVES\Z26X


The default ROM directory INI setting goes in the [GENERAL] section as follows:

rom_dir=d:\a26roms


If you change any of the above items, then you must upload the new Z26X.INI
file to your XBox, load up Z26X, then select "Force Reload D:\\*.ini 
Settings" from the Configuration menu.  Please note that this will overwrite
any of the setting changes you might have made after you first loaded
Z26X.


===============
Menu Navigation
===============

Select menu options with the DPAD or with R/LTrigger.  The speed of 
R/LTrigger movements can be controlled by :

Configuration -> Menu Scroll Speed

There are some places where you can enter or change values.  This 
can usually be done in a variety of ways include DPAD Left/Right, 
R/L Trigger, and L/R Thumb.  Try all of them if the values are changing
too slowly.

"A" selects the highlighted choice.  "B" cancels/returns.
"Y" from a file-select list will go up one directory.


=======
Netplay
=======

In order to netplay with someone, follow these steps:

 - Go to the Configuration menu
 - Select Netplay options
 - Turn netplay on
 - Add a server if you are going to connect to someone else
 - Select the game to play
 - If netplay is on, it will ask you if you want to be the client
   or the server.  One person is the client, and the other is the server.
   If you are the server, the game will wait until the client has
   joined.  If you are the client, make sure the server is ready to accept
   your connection before continuing.  
 - When server starts netplay, you can select a netplay skip value.
   This number specifies how often it should skip checking for network data.
   The higher the number, the less often it checks for network data, but the
   result will be a less responsive controller.
 - Once a connection has been made, it should work fine.

NOTE : You both MUST be using the *EXACT* same game.  
I would be *extremely* surprised if the PAL version of a game
worked via netplay with an NTSC version of the same game.  


The server player is always player 1.  The client player is always player 2.

I don't know how well netplay will work across real networks.  Two xbox's 
on the same intranet work very well, though.

If your connection is lost during gameplay, just wait 30 seconds and
you can return to the game select menu.  (Or you can always reboot...)


=====
SKINS
=====


Instructions for making a new skin:

 - Create a new directory off of your SKINS directory (default skins directory
   is D:\EMUSKINS
 - Place your sound/font/graphic media files in this new directory 
 - Load Z26X
 - "Select Skin" from the main menu and select your new directory.
 - Select Configuration
 - select Configure Skin
 - Use the menus to select your new media files and change your settings
 - When you are satisfied with what you have, go back to the main menu.
 - Select "Configuration"
 - Select "Overwrite D:\*.ini and D:\emuskins\\<skin>\\settings.ini"
   This will write the skin settings in your skin directory (if your skin
   directory is on the hard drive.)
 - You're done!  You can package up the directory and share it with your friends.


If you wish to use sprites in your new skin, then read the following:

 - Create a subdirectory off of your new skin directory called SPRITES
   e.g. D:\EMUSKINS\NEWSKIN\SPRITES
 - In this new SPRITES directory create a 0-based numeric directory for
   each sprite you wish to make.  This means that if you have 4 sprites
   you wish to load, the directory names *must* be called 0, 1, 2, and 3.

   Do not call them 1, 2, 3, and 4.  
   Do not call them 0, 3, 5, 6.  
   Do not call them SPRITE1, SPRITE2, SPRITE3, SPRITE4.  

 - Inside each of these new directories, you must place the sprite frames.
   Each frame is represented by a BMP, PNG, or JPG file.  The order of the
   frames is given by the filenames.  These filenames must also be named
   with 0-based numbers.  For example, 0.png, 1.png, 2.png.  Look at the
   sprites directory of the included default skin to see how it works.

 - Do not skip numbers when naming sprite directories or sprite frame 
   filenames.  A list of directories called 0,1,2,5,7 is *INVALID*.
   Similarly, a list of files called 0.png, 1.png, 4.png, 5.png is also
   *INVALID*.

Also be aware of memory constraints.  Let's say you have a frame of a sprite
called 0.png.  This picture file is 90 pixels wide and 130 pixels high.
This will get rounded up to a 256x256 pixel 32bit picture.  This means
that it will consume 256x256x4 bytes (256KB) of memory.  If your sprite has
10 frames of animation, that's around 2.5MB of memory.  Keep this in mind
before you make ultra-smooth moving sprites with hundreds of frames of
animation.

You can check your available memory by going to Configuration -> Configure Skin
-> Show Available Memory

If you make/configure a skin and Z26X does not load the next time you
play it, then you need to delete the E:\SAVES\Z26X\Z26X.INI and
E:\SAVES\Z26X\SKIN_SETTINGS.INI files.  Z26X should work fine again,
but you'll have to reconfigure your skin.  The problem was probably
that one of your resources (like a WAV or background file) was specified
incorrectly or was never changed from the old skin.  Carefully look at the 
E:\SAVES\Z26X\SKIN_SETTINGS.INI file to make sure that all filenames exist 
in your skin directory.



====================
Controller Remapping
====================

Configuration -> Configure Controllers

There are 32 general/all-purpose emulator "buttons" or actions.  Each of these
buttons can be assigned a specific emulator action.  For example, Emu Button 1
can be A, or B, or DPad Down, etc.  These "emu buttons" can then be assigned 
XBox triggers.  For example, Emu Button 1 (which you have mapped to, for 
example, A) can be triggered by  XBox controller button B.  The default button 
mappings should provide enough information on how the system works and 
how it can be used.  

==========
Autofiring
==========

Configuration -> Configure Controllers -> Controller # -> Change Autofire

Each "Emu Button" can be set up for autofiring.  Simply set the autofire
variable to a non-zero value.  This value indicates how long the emulator
should wait before releasing and re-pressing the button.  A value of 1
might be too fast to register on some games.  I suggest setting it to a
number like 5 first and them fine-tuning it.


======
Combos
======

Setting up a combo can be kind of tricky because you need to know exactly
what the game expects to have happen on the joypads to execute the special
move.  For example, let's say that we want to map a standard move that is
described like this : 

D, DR, R, A

D = Down, DR = Down+Right, R = Right, A = A button

First, set the delay to a number like 2 or 3.  Then set up the moves.  In
this case, any (or none) of the following might work:

Down
Down+Right
Right
Right+A
Right

OR

Down
Down+Right
Right+A

OR

Down
Down+Right
Right
Right+A
Right+A
Right+A


You will probably need to fine-tune each combo move before it works, but
you'll soon get the hang of it.



================
MP3/M3U Playback
================

Simply select the MP3 or M3U file from the game-selection screen.

The M3U file can also just be a regular file with one songfile per line.
For example:

d:\songs\song1.mp3
e:\moresongs\song2.mp3
smb:\mp3s\song3.mp3

If you are making a playlist of songs on your SMB share, then please note
the format:

smb:\mp3s\song3.mp3

The smb:\ tells Z26X to read from your SMB shared directory.  Do not
put the SMB share definition in the filename.

----------SMB shared filenames are case sensitive!!!---------

==============
No Save States
==============

The state-saving functionality is currently not implemented in Z26.


==================================================
Cheating System - How To Make Your Own Cheat Codes
==================================================

Special Note for Z26 - In many Atari 2600 games, certain important values (like
the number of lives you have, etc) are stored as a nibble value.  A nibble is
half of a byte.  For example, in Asteroids your number of lives and the current
direction you are pointing are stored in the same byte.  (High nibble is the
number of lives and the low nibble is the direction.)  When searching for cheat codes,
I would advise using *only* the "equal to" or "not equal to" options.

Just about every single port I've released has this feature, and I 
occasionally hear people asking "how does it work?" This is easiest to 
explain by example:

 1) Start playing a game. 

 2) Go to Options Menu and select "Start Search for Cheat Code"

 3) Go back to game and lose a life

 4) Go to Options Menu and select "Continue Search For Cheat Code"

 5) Select "Search For Values Less Than Before" because when you
    first selected "Start Search For Cheat Codes" you had one more
    life than you do now.  You will see the number of matches go down.

 6) If the number of matches is greater than 10, then perform actions
    3, 4 and 5 continually until the number of matches is less than 10.
    If you run out of lives, then just start playing the game again.
    (Do not exit the emulator and select the game again - just start another
    game from within the emulator.)  Now you will have a full stock of lives,
    which is *more* than the last time you checked your values.  So when you
    continue searching, you'll want to select "Search For Values Greater Than
    Before."  Then go through steps 3-5 over and over until you have less than
    10 matches.

 7) Now that you have less than 10 matches, you can add the codes to your
    list.  If the search narrowed the list down to 1 possible match, it
    will automatically add it to your list.  Now you can "List Cheat Codes"
    and selectively turn on/off the cheat codes to try them out and see
    which on is the right one.

Alternately, you can use the "Search For An Exact Value" option if you
already know the number you wish to change.  Example:

Let's say you are playing Dragon Warrior and your character currently has
25 Hit Points.  Follow these instructions:

 1) Go to Options Menu and select "Start Search for Cheat Code"

 2) Select "Continue Search For Cheat Code"

 3) Select "Search For an Exact Value" and enter 25 as the number.
    The number of matches should decrease very quickly.  

 4) Go back to the game and do something to change your Hit Points amount.
    For example, let's say you drink a potion and your Hit Points are now 35.

 5) Go to options menu and select "Continue Search For Cheat Code"

 6) Select "Search For an Exact Value" and enter 35 as the number.
    Chances are very good that the number of matches will be down to 
    one or two.  Just try out the codes to see which one gives you infinite 
    Hit Points!

Advanced Cheat Code Usage:

Cheat codes have the following format:

TT AAAAAA VVVV

TT     = Type
AAAAAA = Address
VVVV   = Value

You can hand-edit the cheat codes you've created.  Go to the Cheat Code list,
select a code, and select Edit.  Let's say you've already created a cheat code
that keeps your hit points at 25.  The last four hex digits of your code will be
0019 (which is hexidecimal for 25.)  You can change the last two digits to, for 
example, FF which will give you 255 hit points instead of 25.  More sophisticated
codes can be made by altering the Type:

Type Table

80 - Means set the 16-bit value (0-65535) pointed to by the cheat code address 
     to the cheat code value.

30 - Means set the 8-bit value (0-255) pointed to by the cheat code address 
     to the cheat code value.

10 - Means increase the 16-bit value pointed to by the cheat code address
     by the cheat code value.

11 - Means decrease the 16-bit value pointed to by the cheat code address
     by the cheat code value.

20 - Means increase the 8-bit value pointed to by the cheat code address
     by the cheat code value.

21 - Means decrease the 8-bit value pointed to by the cheat code address
     by the cheat code value.

D0 - Means only execute the next code in the list if the 16-bit value pointed
     to by the cheat code address is equal to the cheat code value

D1 - Means only execute the next code in the list if the 16-bit value pointed
     to by the cheat code address is not equal to the cheat code value

D2 - Means only execute the next code in the list if the 16-bit value pointed
     to by the cheat code address is less than the cheat code value

D3 - Means only execute the next code in the list if the 16-bit value pointed
     to by the cheat code address is greater than the cheat code value

E0 - Means only execute the next code in the list if the 8-bit value pointed
     to by the cheat code address is equal to the cheat code value

E1 - Means only execute the next code in the list if the 8-bit value pointed
     to by the cheat code address is not equal to the cheat code value

E2 - Means only execute the next code in the list if the 8-bit value pointed
     to by the cheat code address is less than the cheat code value

E3 - Means only execute the next code in the list if the 8-bit value pointed
     to by the cheat code address is greater than the cheat code value

If you are familiar with cheat codes, you'll notice that these are standard
Gameshark types.  With enough experience you could make some seriously
interesting codes with this system.  

For example, I played around with Super Mario Bros (NES) and found out that
address 0007EE stores the number of coins and address 0007FA is the
one's digit in the timer.  Here are two codes:

E0 0007FA 03
20 0007EE 01

Those codes mean that while the ones timer digit is equal to three, increase the 
number of coins by one.  You won't see the coins updated on the overhead
display in the game, but if you start a game, wait until the timer one's
digit is a three and then collect a coin, you'll see that your coin value
is actually much higher than one, now.  Fun useless stuff.  :P



==================================================
Command-Line/Auto-Launching and Return to Launcher
==================================================

This section is for the developers of frontends, dashboards, etc.

Z26X can be started with parameters to automatically launch a game
at startup.  Example code can be found in the custom_launch_params.cpp file.

There is also example code in that same file that will show you how to 
make Z26X load your frontend/dashboard when it exits.
