[What Was New 004 - August 5, 2008]

Browse Source 
- added: option to disable AA filtering 
         (snes graphics 'crisper', AA now default OFF)
- added: mapped zooming and turbo mode to classic controller
- added: preliminary usb support (loading)
- changed: sram and freezes now saved by filename, not internal romname. 
           If you have multiple versions of the same game, you can now have 
           srams and freezes for each version. A prompt to convert to the 
           new naming is provided for sram only.
- changed: by default, autoload/save sram and freeze enabled

Unzip the archive. You will find the following folders inside:
Unzip the archive into a folder. You'll find 4 variations of the dol for both
wii and gamecube versions. The variants auto save and load preferences and sram
to/from different locations as follows (you can also manually save and load
SRAM to any location).
[A default version is provided for quick install. See loading from HBC below.]
apps Contains Homebrew Channel ready files
(see Homebrew Channel instructions below)
filename preferences/sram autoloading location
------------------------- -------------------------------------
snes9xGX-00x-sd-xxxx.dol SD card
snes9xGX-00x-mcslota-xxxx.dol Memory card in slot A
snes9xGX-00x-mcslotb-xxxx.dol Memory card in slot B
snes9xGX-00x-smb-xxxx.dol SMB share (see SMB section below)
// snes9xGX-00x-noload-xxxx.dol none - doesn't load prefs nor autosave SRAM
executables Contains Gamecube / Wii DOL files
(for loading from other methods)
snes9x Contains the directory structure required for storing
roms, saves, and cheats (see below)
The last part of the filename (shown above as xxxx), denotes the wii and gamecube
versions.
----------------------------
Directory Structure Setup
----------------------------
By default, roms are loaded from "snes9x/roms/", saves and preferences are
stored in "snes9x/saves/", and cheats are loaded from "/snes9x/cheats/".
Therefore you should have the following folder structure at the root
of your load device (SD/USB/SMB):
snes9x/
roms/
saves/
cheats/
----------------------------
ROMS, Preferences, Saves, and Cheats:
ROMS, Preferences, and Saves:
----------------------------
Your SNES rom images must be in the Super Magicom (SMC) or FIG format. Generally,
all images you find will be in this format, but if you run across one that isn't
please download RTOOL which will allow you to convert the image into SMC format.
Cheats must be placed in the cheats folder and named identically to the ROM name,
except with a CHT extension.
Wii
----------
On the Wii, you can load roms from SD card (Front SD or SD Gecko), USB, DVD,
or SMB share. Note that if you are using the Homebrew Channel, to load from
USB, DVD, or SMB you will first have to load Snes9xGx from SD, and then set
your load method preference. To load roms from a Windows network share (SMB)
you will have to edit snes9xGX.xml on your SD card with your network settings,
or edit s9xconfig.cpp from the source code and compile. If you edit and compile
the source, you can use wiiload and the Homebrew Channel to load and play
Snes9xGx completely over the network, without needing an SD card.
On the Wii, you can load roms from any SD card (Front SD, SD Gecko, etc).
By default, ROMs are loaded from "snes9x/roms/" and saves and preferences are
stored in "snes9x/saves/". Therefore, on your SD card, you should have the following
folders:
snes9x/
roms/
saves/
Gamecube
------------
You can load roms from DVD or SD card. If you create a bootable
DVD of Snes9xGx you can put roms on the same DVD. You may save preferences and
game data to SD or Memory Card.
You can load roms from DVD, SD card or SMB share. If you wish to use an SD card
or SMB share, you must create the same folder tree as above. Put your roms in the
"snes9x/roms" folder. On DVD you can either place your roms at the top level, or
optionally you may have an SNESROMS folder at the top level of the DVD, in which
case the game selectorwill default to showing that folder when first entered.
If you create a bootable DVD of Snes9xGx you can put roms on the same DVD.

included in the archive into the root of your SD card (the SD autosaving version
for wii is included in the apps/Snes9xGX/ folder renamed to boot.dol).
Remember to also create the snes9x directory structure required. See above.
Remember to also create the snes9x/roms and snes9x/saves directories. See above.
If you wish to use a version that autosaves to other available saving locations,
just choose the appropriate dol, copy it into the apps/Snes9XGX/ folder, and
RENAME it to boot.dol (remove the other version). Then proceed to copy
the entire apps folder to your sd card and run it with the HBC.

Gamecube:
---------
You can load Snes9xGX via sdload and an SD card in slot A, or by streaming
it to your Gamecube, or by booting a bootable DVD with Snes9xGX on it.
This document doesn't cover how to do any of that. A good source for information
on these topics is the tehskeen forums: http://www.tehskeen.com/forums/

GameCube. You can get more information on SNES9X here from the below URL.

Make sure you enable the superscope, mouse, or justifier in the controller
options menu BEFORE loading the rom. If you have already loaded the rom
and changed the setting, reset the game for the settings to take effect.
These controllers can be controlled by either the Gamecube controller analog
sticks,the Classic controller analog sticks, or by aiming at the screen
with the wiimote.
Aim Offscreen - Wiimote Minus, GameCube Z button
Fire - B button
Cursor - A button
Turbo Toggle - Wiimote D-Pad Down, GameCube Y button
These configurations cannot be changed.

Snes9xGx now includes the ability to load SRAM from Snes9x on other

Snes9xGx 2.0.1 now includes the ability to load SRAM from Snes9x on other
platforms (Mac/PC/Linux/Etc) and to save back to those platforms. To use this
feature simply save or load SRAM to/from SD card or an SMB share.
To load a SRAM file on the Wii or Gamecube from another platform, ensure the
name of the SRM file matches the filename of the ROM (except with an SRM
extension).
The only thing to be aware of is that Snes9xGx requires that the SRM file have a
name that is the rom name (not necessarily the same as the file name!) with .SRM
at the end. For example, the game "Super Mario All-Stars + World" has a rom name
of "ALL_STARS + WORLD", so the SRAM file should have the name "ALL_STARS +
WORLD.srm". You can see the rom name for a game by loading the game - the rom
name is shown in the information that is briefly shown at the bottom of the
screen. A perhaps easier way to find the correct name is simply to load the game
and then save SRAM to SD or SMB and look at the filename that Snes9xGx uses.
That's the name you should use when importing an SRAM from another platform.
To use a Wii/GameCube SRAM file on another platform just do the opposite:
copy the saved SRAM file to the other platform. You may have to rename the
file to be what that version of snes9x expects it to be.

*
* Notes:
*
* This implementation was created by studying many existing examples
* found in Open Source, in the public domain, and in various documentation.
* The SMB protocol makes minimal use of the DES function, so this is a
* minimal implementation. That which is not required has been removed.
*
* The SMB protocol uses the DES algorithm as a hash function, not an
* encryption function. The auth_DEShash() implemented here is a one-way
* function. The reverse is not implemented in this module. Also, there
* is no attempt at making this either fast or efficient. There is no
* need, as the auth_DEShash() function is used for generating the LM
* Response from a 7-byte key and an 8-byte challenge. It is not intended
* for use in encrypting large blocks of data or data streams.
*
* As stated above, this implementation is based on studying existing work
* in the public domain or under Open Source (specifically LGPL) license.
* The code, however, is written from scratch. Obviously, I make no claim
* with regard to those earlier works (except to claim that I am grateful
* to the previous implementors whose work I studied). See the list of
* references below for resources I used.
*
* References:
* I read through the libmcrypt code to see how they put the pieces
* together. See: http://mcrypt.hellug.gr/
* Libmcrypt is available under the terms of the LGPL.
*
* The libmcrypt implementation includes the following credits:
* written 12 Dec 1986 by Phil Karn, KA9Q; large sections adapted
* from the 1977 public-domain program by Jim Gillogly
* Modified for additional speed - 6 December 1988 Phil Karn
* Modified for parameterized key schedules - Jan 1991 Phil Karn
* modified in order to use the libmcrypt API by Nikos Mavroyanopoulos
* All modifications are placed under the license of libmcrypt.
*
* See also Phil Karn's privacy and security page:
* http://www.ka9q.net/privacy.html
*
* I relied heavily upon:
* Applied Cryptography, Second Edition:
* Protocols, Algorithms, and Source Code in C
* by Bruce Schneier. ISBN 0-471-11709-9, John Wiley & Sons, Inc., 1996
* Particularly Chapter 12.
*
* Here's one more DES resource, which I found quite helpful (aside from
* the Clinton jokes):
* http://www.aci.net/kalliste/des.htm
*
* Finally, the use of DES in SMB is covered in:
* Implementing CIFS - the Common Internet File System
* by your truly. ISBN 0-13-047116-X, Prentice Hall PTR., August 2003
* Section 15.3, in particular.

* Perform S-Box substitutions.
*
* Input: dst - Destination byte array into which the S-Box substituted
* bitmap will be written.
* src - Source byte array.
*
* Output: none.
*
* Notes: It's really not possible (for me, anyway) to understand how
* this works without reading one or more detailed explanations.
* Quick overview, though:
*
* After the DataExpansion step (in which a 32-bit bit array is
* expanded to a 48-bit bit array) the expanded data block is
* XOR'd with 48-bits worth of key. That 48 bits then needs to
* be condensed back into 32 bits.
*
* The S-Box substitution handles the data reduction by breaking
* the 48-bit value into eight 6-bit values. For each of these
* 6-bit values there is a table (an S-Box table). The table
* contains 64 possible values. Conveniently, a 6-bit integer
* can represent a value between 0 and 63.
*
* So, if you think of the 48-bit bit array as an array of 6-bit
* integers, you use S-Box table 0 with the 0th 6-bit value.
* Table 1 is used with the 6-bit value #1, and so on until #7.
* Within each table, the correct substitution is found based
* simply on the value of the 6-bit integer.
*
* Well, the original algorithm (and most documentation) don't
* make it so simple. There's a complex formula for mapping
* the 6-bit values to the correct substitution. Fortunately,
* those lookups can be precomputed (and have been for this
* implementation). See pp 274-274 in Schneier.
*
* Oh, and the substitute values are all 4-bit values, so each
* 6-bits gets reduced to 4-bits resulting in a 32-bit bit array.

*
* Notes:
*
* This implementation was created by studying many existing examples
* found in Open Source, in the public domain, and in various documentation.
* The SMB protocol makes minimal use of the DES function, so this is a
* minimal implementation. That which is not required has been removed.
*
* The SMB protocol uses the DES algorithm as a hash function, not an
* encryption function. The auth_DEShash() implemented here is a one-way
* function. The reverse is not implemented in this module. Also, there
* is no attempt at making this either fast or efficient. There is no
* need, as the auth)DEShash() function is used for generating the LM
* Response from a 7-byte key and an 8-byte challenge. It is not intended
* for use in encrypting large blocks of data or data streams.
*
* As stated above, this implementation is based on studying existing work
* in the public domain or under Open Source (specifically LGPL) license.
* The code, however, is written from scratch. Obviously, I make no claim
* with regard to those earlier works (except to claim that I am grateful
* to the previous implementors whose work I studied). See the list of
* references below for resources I used.
*
* References:
* I read through the libmcrypt code to see how they put the pieces
* together. See: http://mcrypt.hellug.gr/
* Libmcrypt is available under the terms of the LGPL.
*
* The libmcrypt implementation includes the following credits:
* written 12 Dec 1986 by Phil Karn, KA9Q; large sections adapted
* from the 1977 public-domain program by Jim Gillogly
* Modified for additional speed - 6 December 1988 Phil Karn
* Modified for parameterized key schedules - Jan 1991 Phil Karn
* modified in order to use the libmcrypt API by Nikos Mavroyanopoulos
* All modifications are placed under the license of libmcrypt.

* Protocols, Algorithms, and Source Code in C
* by Bruce Schneier. ISBN 0-471-11709-9, John Wiley & Sons, Inc., 1996
* Particularly Chapter 12.
*
* Here's one more DES resource, which I found quite helpful (aside from
* the Clinton jokes):

TinySMB-GC 0.1
May 2006
Developer Documentation
What is TinySMB-GC?
TinySMB-GC is a minimal implementation of the SMB protocol for the Nintendo Gamecube.
What does it do?
Essentially, TinySMB-GC enables network share support. This means that it will allow the
GameCube to connect to a shared folder on a Windows XP or linux samba box, and perform
basic file functions.
Known Restrictions
TinySMB-GC only supports the LM1.2X002 protocol. THIS IS NOT THE MOST SECURE!
However, it does NOT transmit your password over the wire, so it's reasonably safe.
How do I use it?
TinySMB-GC is developed with devkitPPC and libOGC, therefore you should be using this
development environment. Put simply, it won't work with anything else!
TinySMB-GC uses the TCP-raw form of SMB on port 445.
The Functions.
int SMB_Init (char *user, /*** The logon user - MUST have share access rights ***/
char *password, /*** PLEASE USE PASSWORD SECURITY! ***/
char *client, /*** Machine ID, whatever you want to call the GC ***/
char *server, /*** Machine ID of share server ***/
char *share, /*** Share ID ***/
char *IP); /*** IP of share server ***/
SMB_Init is used to establish the connection, authenticate and attach to the share.
Obviously, this must be called successfully before any other function.
void SMB_Destroy ();
SMB_Destroy takes care of releasing the internal socket of TinySMB-GC and should be
called when the SMB functions are no longer required.
int SMB_FindFirst (char *filename, /*** The file mask to search for ***/
unsigned short flags, /*** Search criteria flags ***/
SMBDIRENTRY * sdir); /*** An SMBDIRENTRY to hold directory information ***/
Similar to MS-Windows, to search for a file or directory, use this function to determine if the
file already exists. The SMBDIRENTRY simply holds basic information on each entry retrieved.
int SMB_FindNext (SMBDIRENTRY * sdir);
Called to continue a search started with SMB_FindFirst.
int SMB_FindClose ();
When all searches have completed, call SMB_FindClose to dispense with the search handle.
SMBFILE SMB_Open (char *filename, /*** The filename to open ***/
unsigned short access, /*** Access method ***/
unsigned short creation); /*** Creation flags ***/
This call will open a file on the share. Both reading and writing are supported.
Look at smb.h for information on the access and creation flags.
void SMB_Close (SMBFILE sfid);
Close a file previously opened with SMB_Open
int SMB_Read (char *buffer, int size, int offset, SMBFILE sfile);
Read from the file opened with SMB_Open.
int SMB_Write (char *buffer, int size, int offset, SMBFILE sfile);
Write to the file opened with SMB_Open.
NOTE: The offset value provides the missing seek function. However, the onus
is on the developer to maintain the offset value when reading / writing
sequentially.
You should also be aware that these functions should only be used to read/write
blocks up to 62Kbytes. Although it allows reading and writing of 4Gb files, it
does not support blocks larger then 16-bit - go figure!
