NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v16

http://xport.xbox-scene.com

what's new:

- New (and very excellent) skin by J-RED

- New game configuration option : Overclock M68000 CPU feature
- Prevents slowdown on games like Sonic when lots of sprites are on-screen

============
INSTALLATION
============

If you are a first-time NeoGenesis user, simply upload all the files to a directory
on your XBox and run the default.xbe file.

If you are a previous user of NeoGenesis, you need to first delete the
E:\SAVES\NEOGENESIS\SKIN_SETTINGS.INI file. Then you need to completely
remove your existing EMUSKINS directory and replace it with the new one in
this package.

If you don't follow those instructions, you will get a very weird looking
display. If that happens, go to "Configuration" -> "Video/Skin Configuration" ->
"Select Skin" and select the default_neogenesis skin. Things should then
be back to normal.


================
OVERCLOCKING CPU
================

Now there's yet another reason why NeoGenesis is even better than a real
Genesis/Megadrive machine! smile.gif

Ever notice in lots of games like Sonic and Strider that sometimes things will
slow down when lots of sprites are on the screen? This happens on the real
hardware, too. Now there's a way to correct that problem.

Go to the game selection menu, highlight a game, and press X to bring up the
game configuration menu. There is a new option called "Overclock M68000".
If you turn it on, you should notice that there is no more slowdown.

You can also turn on/off this overclocking from within the game. While the
game is playing, press the right thumb stick to bring up the in-game menu.
Select "Configuration", "Configure Controllers", "Controller 1",
"Change Emulator Definitions" and assign one of the emu buttons to be
"Toggle CPU Speed". Now go to "Change Joypad Mappings", "Change Game Mappings"
and change the button mapping for "Toggle CPU Speed". Now you can use that
button mapping to turn the CPU Overclocking on/off in the game so you can
better see the effects.

Most games don't suffer from any slowdown, so the overclocking option is
off by default.

It also doesn't work well with 32x or SegaCD games. SegaCD games cannot even start
if the overclocking option is on at startup. You'll need to toggle it on/off from
within the game.

WARNING : It is possible to put the emulator into an undefined state when using
the CPU Overclocking on 32x and/or SegaCD games. The symptoms of this are
stuttering music and halted gameplay. If this happens, you'll need to restart
NeoGenesis. If you just use the overclocking on regular non-32x, non-segacd games,
everything should stay fine.

NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v13

http://xport.xbox-scene.com

What's New:

- Fixed relax+linux bugs

- If you were having Linux+Relax or Samba issues, then I suggest you try
this version of NeoGenesis. If this fixes the problems people have been
having, then the changes will go into all the ports I've done. If not, then
I probably will not bother...so I need to hear feedback.

NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v12

http://xport.xbox-scene.com

What's New:

- Memory corruption fix when loading Sega CD games. If you were having problems with
certain SegaCD games not working (e.g. Secret of Monkey Island, or anything, really)
then this should probably fix it. Some debugging code was left in and if the
filename length of your SegaCD files was more than about 65 characters (including the
path) then there would be a buffer overflow. So if you had a long filename like
E:\\GAMES\\SEGA\\SEGACDS\\SECRET_OF_MONKEY_ISLAND\\SECRET_MONKEY_ISLAND_02.MP3
then things would get screwy.

- Support for Linux Relax sharing
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.


- If you were having Linux+Relax or Samba issues, then I suggest you try
this version of NeoGenesis. If this fixes the problems people have been
having, then the changes will go into all the ports I've done. If not, then
I probably will not bother...so I need to hear feedback.

This is also a customizable controller action while in-game. Configure it
via the Controller Configuration -> UI Mappings menu.

- Can now save any string setting (like Samba/Relax share names) and directory
locations via menus. To change Samba/relax share names, go to Configuration ->
Network/Netplay Configuration. To change the default directories, go to
Configuration -> Change Default Directories

NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v10


http://xport.xbox-scene.com/


What's New:

- PAL50 support was broken in v8 and fixed in v9, but v9 broke 4x filters and would hang
whenever trying to change XBox filters. This is fixed.

- 4x Filters removed because most of them ran too slowly to be playable on any game and the
ones that were playable didn't appear to give much ( if any ) improvement to graphics.
If anyone objects, I'll listen to arguments for re-installing it.

- Selectable throttle speed - now you can control how fast the throttle/fast forward
option behaves.

- Several new transition effects. Currently, the transition effect is set to "random". If you
want to set the transition effect to a specific setting, then go to Main Menu -> Configuration ->
Configure Skin -> Transition Effect. If you don't want to see any transitions, then set
the Transition Speed to 0 on the same menu.

- Changed memory management of background textures. This results in more free memory allowing
for more/larger skin media. (This is really only of interest to people making skins.)


-----------------------------------------------------------------------

NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v9


http://xport.xbox-scene.com/


What's New:

- PAL50 support was broken in v8 ; fixed

- Fixed Relax bug - now sharenames like $ROOT$ShareName work

- Sorting is not case sensitive anymore

- Forgot to mention - in v8 pressing DPAD Left/Right moves by letter
on the file selection screens. Move LTHUMB Left/Right to change
screenshots.


-----------------------------------------------------------------------

NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v8


http://xport.xbox-scene.com/


What's New:

- 480p, 720p, 1080i support

- 4x varieties for all filters
+ Most of these 4x filters make the games run too slow to be enjoyable,
but the AdvanceMame4x runs well and so do a few others.
+ I also suggest not using the 4x filters unless you can use
720p or 1080i modes. Scrunching a 1280x960 picture to half that size
looks almost exactly the same as the 2x version (and perhaps a little
worse because of the scrunching.)

- Hardware filtering options : Point, Bilinear, Trilinear, Anisotropic

- Access new video options from Main Menu -> Configuration -> Video Configuration

- Re-vamped the 50/60, tearing, jittery sound, etc. Hopefully this should
straighten out all the weird, misc bugs a few people have encountered when
trying to play PAL games on NTSC XBox or vice versa.



-----------------------------------------------------------------------

NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v7


http://xport.xbox-scene.com/


What's New:
- Fixed bug where CDDA music would get turned back ON/OFF incorrectly when
returning from Options Menu
- Improved real-CD buffering so if your CD is scratched/damaged, it
should still play smoothly
- Added new Configuration Option : Fix Tearing
+ Default is Auto - which means tearing is always fixed unless the game is playing
consistently less than max FPS. Set it to "Always" if you never want to
see screen tearing. For certain 32x games, this will result is a slightly
lower/choppier framerate. Set it to "Never" to get the best possible speed
and smooth framerate but you may see screen tearing.
- New UI Feature - Auto Load Most Recent Save State
+ Turn this option on via the Main Menu -> Configuration menu
+ If it's on, then when you launch a game, the most recently saved
state will automatically be loaded.



-----------------------------------------------------------------------


NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v6


http://xport.xbox-scene.com/


What's New:
- Fixed bug in save states when playing from ISO/MP3.
If you saved a game while it was playing an MP3, continued playing
until it loaded another MP3, and then reloaded the save state from the
other MP3, NeoGenesis would crash. This is fixed.



-----------------------------------------------------------------------


NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v5


http://xport.xbox-scene.com/

Sorry about the "two releases in 30 minutes" thing....but I think you'll like this one:

What's New:
- Save States for CD games are now working (!)
This is a feature even the windows version of Gens does not have. smile.gif



-----------------------------------------------------------------------


NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v4


http://xport.xbox-scene.com/


What's New:
- Fixed video slowdown in 32x games. Very nice FPS in Virtua Fighter 32x and
all other 32x games now.
- Other bugfixes that were fixed in other UI-similar releases. (E.g. long
filenames in network shares, etc)

-----------------------------------------------------------------------


NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v3

What's New:
- Fixed screen tearing


-----------------------------------------------------------------------



NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v2

what's New:

- Bug fix - rompath INI setting was not being read
- Sound fix for everyone experiencing "fast sound" (i.e. the people running
50hz games on in 60hz XBox mode.)
- New Skin options :
+ Continuously loop sprite animations or just loop once
+ Assign motion_x and motion_y variables
+ Assign a bounding rectangle in which sprites can move
+ Assign a degree of rotation that the sprites should turn when they hit a boundary

Enjoy!

a new frontend, that frontend could launch NeoGenesis and when you exit
NeoGenesis, that frontend can be automatically reloaded.

- Flapjack and a cigarette


Various Important Notes:

============
Saving Games
============

This is a common pitfall with XBox emulators of consoles that use SRAM.
If you are playing, for example, Phantasy Star, then when you have saved the game,
you must go back to the game select menu.

If you just turn off your XBox while you are still playing the game, then
your saves will not be written to the XBox hard drive and it will be like you
never saved your game.


---------------------------------------------------------------
CUE sheet processing/CDDISSECT friendly
---------------------------------------------------------------

I've improved (IMHO) the original CD track processing by
allowing for the input of a CUE sheet. The original GENS source code calculates
CD track lengths by making a best calculation of the length of the MP3 files.
This, however, is not always accurate. If you have many MP3 tracks on a CD, the
track offsets grow increasingly incorrect. Using a CDDISSECT-made CUE sheet
results in 100% accuracy. (So I suggest you use it.) Additionally, this port
of GENS is completely CDDISSECT friendly - meaning that you can pop a CD into
your computer, run CDDISSECT, upload all the files (without renaming anything)
and run the CUE sheet on XBox. If you run the CUE sheet, you do not need to
rename the ISO file to remove the "01" at the end of the name. However, if
you try to run the ISO file, it will not find the MP3 tracks (unless you first
rename the ISO file to remove the "01".) If you have existing CD images on your
XBox that worked with another port of GENS, then they will also work with this
one.

============================================
Notes From Gens Documentation About Settings
============================================

Gens now features a custom YM2612 (main sound chip) sound core which
features a "High Quality" mode. The sound output is more accurate
in HQ mode, but it slows things down a bit.

Gens also features an "improved" DAC (part of the YM2612) sound mode.
This makes the sound in a few games, ( e.g. Street Fighter 2), much better
than it would be on real hardware. However, it also causes bugs in other games
so you should leave it turned off most of the time.

Tere is optional PSG sound "improvement". This changes the PSG sound
output from Square waves to Sine waves which is technically incorrect but can
make some games sound better. Again you should leave this turned off unless you
really hate the normal PSG sound.

The 2 SH2 processors can take up to 75% of the emulation time !
To gain some FPS, Gens offers the possibilities to change
MSH2 and SSH2 CPU clocks from 0% to 100%.

Replace 100 by a lower value to speed up the 32X emulation.
100 means SH2 runs at 23 Mhz and 0 means 0 Mhz... easy smile.gif
Gens doesn't emulate some wait states presents in the real 32X hardware so
you can decrease the master CPU to 60 for almost all games without affecting the
in-game speed.

Slave CPU is mainly used for sound emulation (except for some games with
many 3D calculations such as Virtua Racing), so you can decrease it if you think
PWN sound isn't important.


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

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

rlxshare=c:\sgenroms@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 NeoGenesis.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 NeoGenesis 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 NeoGenesis.INI, you have to do a
"Force Reload of D:\*.INI" from the Configuration Menu or else the changes
you made to NeoGenesis.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 NeoGenesis.INI file included in
the package:

Note - you do not need to change the defaults in the INI that comes packaged
with NeoGenesis in order for NeoGenesis to run. These are all *optional*.

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\NEOGENESIS. Goes in [GENERAL] section. Example:

save_dir=E:\SAVES\NEOGENESIS


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

rom_dir=d:\sgenroms


If you change any of the above items, then you must upload the new NeoGenesis.INI
file to your XBox, load up NeoGenesis, 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
NeoGenesis.


===============
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.


=====
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 NeoGenesis
- "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 NeoGenesis does not load the next time you
play it, then you need to delete the E:\SAVES\NEOGENESIS\NEOGENESIS.INI and
E:\SAVES\NEOGENESIS\SKIN_SETTINGS.INI files. NeoGenesis 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\NEOGENESIS\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 NeoGenesis to read from your SMB shared directory. Do not
put the SMB share definition in the filename.

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


=======
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...)


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


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. tongue.gif



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

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

NeoGenesis 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 NeoGenesis load your frontend/dashboard when it exits.




Enjoy!
