The Daodan DLL is a modification for Oni that hooks into the game engine and applies bug fixes and patches. It also replaces parts of the engine with its own code. Daodan fixes many issues, including the famous "[[Blam|Blam!]]" error that occurs on many Windows XP machines. It also adds new features such as support for extra screen resolutions (including many widescreen resolutions) and bonus cheat codes.
{{Hatnote|This is about a Windows-only patch for the game engine. For the entity within the game's story, see [[Daodan]]. For information on the patches to Mac versions of Oni and historical patching of Windows Oni, see the [[:Category:Patches|Patches category]]. Also see [[OniX]], a rebuild of the Oni application for modern Windows systems.}}
The '''Daodan DLL''' is a patch for Oni for Windows that hooks into the game engine to fix bugs and add features. It does this by posing as '''binkw32.dll''', the library that Oni loads so that it can play the game's opening and ending videos. The Daodan fixes issues such as the famous "[[Blam|Blam!]]" error that occurs on modern machines. It also adds new features such as support for widescreen resolutions and bonus cheat codes. The Daodan DLL was created by [[User:SFeLi|SFeLi]] and then developed further by [[User:RossyMiles|RossyMiles]], [[User:Gumby|Gumby]] and [[User:Admin|Alloc]].

==Installation Instructions==
Note that you '''already have the Daodan DLL installed''' if you installed the [[Anniversary Edition]].
#Before installation, it is important to know where your copy of Oni has been installed to. For most people, it is stored in "C:\Program Files\Oni" (My Computer -> Local Disk (C:) -> Program Files -> Oni). This folder should contain a "GameDataFolder" and "Oni" or "Oni.exe".
#It is important that you use an "Oni.exe" that is compatible with Daodan. If you are using the FASM-Daodan, Oni will not start unless you have the correct EXE. If you are using the recommended version of C-Daodan, Oni will start, but most of the features of Daodan will not be present.
#Back up your Oni.exe and binkw32.dll files by renaming them (e.g. "Oni-original.exe").
#Place the newly-downloaded Oni.exe, binkw32.dll (and realbink.dll, if provided) in the folder with Oni.exe.


==Testing==
===Manual installation instructions===
To test if you have done everything correctly, run "Oni.exe". Enter the pause (Diary) screen (F1 by default) and type "tellmetheversion"; if you get a result like "Daodan v.3.0", the DLL is working.
:'''''(For non-AE users)'''''
1. You'll have to extract the Daodan DLL files yourself from the AE package [http://mods.oni2.net/node/233 here]. The files you need are in the plain\win_only\ directory.<br />
2. Extract the Oni.exe meant to go with the Daodan DLL from the AE package [http://mods.oni2.net/node/231 here].<br />
3. Find where your copy of Oni has been installed on your hard drive; usually it's "C:\Program Files\Oni\". This folder should contain GameDataFolder and Oni.exe (just called "Oni" if you have file extensions hidden). Back up this Oni.exe by renaming it (e.g. "Oni-original.exe").<br />
4. Place the newly-downloaded Oni.exe, binkw32.dll, realbink.dll, and assorted files into the Oni\ folder.<br />
5. To confirm that you have done everything correctly, run Oni.exe. Enter the game, bring up the Data Comlink (F1 by default), and type "tellmetheversion"; if you get a result like "Daodan v.''x.y''", the DLL is working.


==C-Daodan==
===Troubleshooting===
This is the recommended version of the Daodan DLL. This is also the only version that supports windowed mode.
If the game does not display correctly (for instance, a black window), try the following in any order:


[http://mods.oni2.net/node/233 Download C-Daodan (binkw32.dll)] <big>—></big> [http://mods.oni2.net/node/231 Use with this version of the game app] (you probably already have it)
1. Disable the intro movie by renaming GameDataFolder\intro.bik. This often fixes the game window.<br />
2. Open the daodan.ini in Notepad and set either "daodangl" or "windowhack" to true. "windowhack" should at least center the window on the screen.<br />
3. Try [http://www.google.com/search?q=windows+run+as+administrator launching Oni as Administrator].<br />
4. Make the Oni folder writable by un-checking "Read-only" in the Properties window for the folder.<br />
5. Try both the run_full and run_wind scripts.
 
You can report problems with the Daodan DLL on [{{Discord}} our Discord server].

===Settings===
===Languages===
====Patches====
The Daodan DLL offers support for the Chinese version of the game as well as multibyte languages in general (see "multibyte" under {{SectionLink||All configuration settings}}). It also adds some basic localization support by allowing cheat code names and two hardcoded strings in Oni to be translated.
Creating a file called Daodan.[[wikipedia:INI_file|ini]] in the same directory as the Daodan DLL will allow you to enable/disable the patches inside Daodan. It can also be used to store configuration settings and language items. Each setting is stored inside a section as a name and value pair.


To enable a patch, look for the patches section in your Daodan.ini. If the patches section doesn't exist, create it by typing
[Patch]
at the end of your file.
You can now enable or disable patches by typing the patch name followed by '''=True''' or '''=False''' (caps and spacing don't matter). For example, let's say you want to turn off the cooldown timer patch (so you can drop and pick up the Mercury Bow after firing to fire again immediately) and the new windowed mode makes your game crash or makes it run slowly:
[Patch]
CooldownTimer = False
WindowHack = False
All patch names are found in the "All patches" section below.
====Options====
With an unpatched Oni, the only way to change settings such as windowed mode was to create a batch file (.bat) and type command line options into it. In the beta Daodan, options can be added to the Daodan.ini. To add an option, look for the options section or type
[Options]
at the end of your Daodan.ini.
To enable windowed mode by default, type:
[Options]
Switch = False
Similarly, to disable sound, add the line:
[Options]
Switch = False
Sound = False
A list of options can be found in the "All options" section below.
====Languages====
The Daodan DLL offers support for the Chinese version of the game as well as multibyte languages in general (see "multibyte" under "Patches" section). It also has the beginnings of some basic localization support, by allowing cheat code names and other strings to be translated. To add an option, look for the options section or type
[Language]
To enable Chinese support, type:
To enable Chinese support, type:
  [Language]
  [language]
  Chinese = True
  Chinese = True
This will load a DLL called xfhsm_oni.dll (apparently provided with Chinese copies of Oni).
This will load a DLL called xfhsm_oni.dll (provided with a Chinese copy of Oni in order to load the Chinese font that also comes with it).

====Command-line arguments====
====Locales====
[[Customizing#Command-line_arguments|Command line options]] are still present in the beta Daodan although the syntax is a little different (and a bit more powerful.) The basic syntax for a command line option is this:
In order to use the "savepoint" and "syndicatewarehouse" settings above, you must create a locale:
-<ini section>.<name> <value>
:1. Add a setting called "language" under the daodan.ini's [language] section with the name of your locale, e.g.:
Where <ini section> is the Daodan.ini section (usually '''Patch''' or '''Options''',) <name> is the option and <value> is the value to set it to (usually '''True''' or '''False'''.) Therefore, to disable sound, start Oni with this:
[language]
language = xx
:You can call the locale whatever you want and it need not be an official ISO locale code such as "en" or "pt", but [[wp:List of ISO 639 language codes|here's the list of language codes]] if you want it.
:2. Create a folder alongside the Daodan DLL called "daodan_locales".
:3. Create an INI file inside called xx.ini (or whatever you called your locale in step 1).
:4. The contents of the INI should be:
savepoint = ''translation''
syndicatewarehouse = ''translation''
The next time Oni runs, you should see your translated strings in the Load Game screen. This approach allows you to create/download as many locale INIs as you want, place them in daodan_locales, and switch between them by changing the "language" setting in daodan.ini.
 
===Configuration===
Creating a plain-text file called "daodan.[[wp:INI file|ini]]" in the same directory as the Daodan DLL will allow you to configure which patches are enabled, as well as to store configuration settings and language items. This file is typically created by the Daodan DLL the first time it loads.
 
On modern versions of Windows (starting with Windows Vista), Oni does not properly request write access to the directory containing Oni.exe (i.e. C:\Program Files (x86)\Oni in typical installs). Windows detects this, and creates a dedicated directory for Oni.exe (and thus the Daodan DLL) to write its files to, located in C:\Users\<Your Username>\AppData\Local\VirtualStore. The directory for Oni will mirror its relative path on disk, so in a typical install it will be at VirtualStore\Program Files (x86)\Oni. This is where all files output by the program (startup.txt, persist.dat, key_config.txt, etc.) will be located when Oni is not run as an administrator. '''This is the location where daodan.ini must be placed if Oni is to be run as a non-administrator.''' Note that you can create your own folder for Oni, e.g. C:\Games\, to avoid this permissions issue.
 
Inside of the daodan.ini file, each configuration setting is stored inside a section as a name-value pair. To temporarily disable a setting in the INI, add a '#' to the beginning of the line and the Daodan will ignore it. Any settings not listed in the INI will use their default values which are listed in {{SectionLink||All configuration settings}}. To change a setting away from its default, add the setting to the relevant section. If the section does not yet exist, add it to the end of the file and add relevant entries under it. Entries are case-<u>in</u>sensitive and spacing does not matter.
 
Here is a simple example of a daodan.ini file:
[devmode]
highres_console = True
showtriggervolumes = True
[gameplay]
cooldowntimer = False
 
daodan.ini may contain the following sections:
* devmode ''(Developer Mode Configuration)''
* gameplay ''(Gameplay Configuration)''
* graphics ''(Graphics Configuration)''
* language ''(Language Configuration)''
* modding ''(Modding Configuration)''
* oni ''(Original Oni Options Configuration)''
* windows ''(OS Interaction Options)''
 
For information on all possible settings, see {{SectionLink||All configuration settings}}.
 
===Command-line arguments===
[[Customizing#Command-line arguments|Command line options]] for the Daodan DLL can also be used when launching Oni, although the syntax is a little different (and a bit more powerful). The basic syntax for a command line option is this:
-<ini section>.<option> <value>
For example, to disable sound start Oni with this:
  oni -options.sound false
  oni -options.sound false
When <ini section> is omitted, it is assumed to be '''options'''. When <value> is omitted, it is assumed to be '''true''' unless <name> starts with '''no''' (eg. '''nosound''') in which case it is assumed to be '''false'''. So an easier way to write the above command would be:

  oni -nosound
  oni -nosound
Options or patches specified on the command line take precedence over options specified in Daodan.ini. Currently Oni's command line parser isn't powerful enough to parse language elements (no support for quoting arguments); this will be fixed in a later release.

===Developer Mode===
===Added input bindings===
The DLL enables [[Developer Mode]]; go to the pause screen (F1) and type "thedayismine" or simply 'x' to activate it.
When Daodan Input is enabled, the following inputs can be bound in key_config.txt in addition to the [[Customizing/Binding#Bindable key names|usual ones]].
 
===Custom screen resolutions===
If you wish to run in a screen resolution that is not available and you are running the recommended version of C-Daodan, create a text file (Notepad document) called "res.txt" in your Oni folder (C:\Program Files\Oni) containing a list of custom resolutions in this format (one resolution per line):
 
800x600<br />
1024x600<br />
1024x768
 
==FASM-Daodan (old)==
There is also a much older release of Daodan, referred to as FASM-Daodan. This is the original version by SFeLi. Unlike the C-Daodan, FASM-Daodan requires a different DLL to be downloaded depending on which Oni.exe is used. It does not support the newer Daodan features, such as windowed mode and custom resolutions, however it still contains the basic patches such as the Windows XP patch and the custom cheats.

This is about a Windows-only patch for the game engine. For the entity within the game's story, see Daodan. For information on the patches to Mac versions of Oni and historical patching of Windows Oni, see the Patches category. Also see OniX, a rebuild of the Oni application for modern Windows systems.

The Daodan DLL is a patch for Oni for Windows that hooks into the game engine to fix bugs and add features. It does this by posing as binkw32.dll, the library that Oni loads so that it can play the game's opening and ending videos. The Daodan fixes issues such as the famous "Blam!" error that occurs on modern machines. It also adds new features such as support for widescreen resolutions and bonus cheat codes. The Daodan DLL was created by SFeLi and then developed further by RossyMiles, Gumby and Alloc.

Subpages: Change log

Note that you already have the Daodan DLL installed if you installed the Anniversary Edition.

Manual installation instructions

(For non-AE users)

1. You'll have to extract the Daodan DLL files yourself from the AE package here. The files you need are in the plain\win_only\ directory.
2. Extract the Oni.exe meant to go with the Daodan DLL from the AE package here.
3. Find where your copy of Oni has been installed on your hard drive; usually it's "C:\Program Files\Oni\". This folder should contain GameDataFolder and Oni.exe (just called "Oni" if you have file extensions hidden). Back up this Oni.exe by renaming it (e.g. "Oni-original.exe").
4. Place the newly-downloaded Oni.exe, binkw32.dll, realbink.dll, and assorted files into the Oni\ folder.
5. To confirm that you have done everything correctly, run Oni.exe. Enter the game, bring up the Data Comlink (F1 by default), and type "tellmetheversion"; if you get a result like "Daodan v.x.y", the DLL is working.

Troubleshooting

If the game does not display correctly (for instance, a black window), try the following in any order:

1. Disable the intro movie by renaming GameDataFolder\intro.bik. This often fixes the game window.
2. Open the daodan.ini in Notepad and set either "daodangl" or "windowhack" to true. "windowhack" should at least center the window on the screen.
3. Try launching Oni as Administrator.
4. Make the Oni folder writable by un-checking "Read-only" in the Properties window for the folder.
5. Try both the run_full and run_wind scripts.

You can report problems with the Daodan DLL on our Discord server.

Feature summary

  • Buffer overflow patch – Fixes Oni crashing at startup on modern computers.
  • Windowed mode – Oni can run inside a window properly.
  • Custom screen resolutions – Includes many more possible screen resolutions.
  • BGRA32 (ARGB8888) texture support.
  • Extra cheats – See § Added cheat codes.
  • Cheats always enabled – No need to beat game first.
  • Extra command-line options (for advanced users) – For a list, type "Oni -help".
  • A new input system based on Raw Input, which should fix mouse lag and judder, as well as disabling mouse acceleration.
  • AIs have ability to properly dodge projectiles.
  • Stops fly-in character portraits from being stretched when playing in widescreen resolutions.
  • Enables Developer Mode – Enter the Data Comlink and type "thedayismine" or simply 'x' to activate it.

Languages

The Daodan DLL offers support for the Chinese version of the game as well as multibyte languages in general (see "multibyte" under § All configuration settings). It also adds some basic localization support by allowing cheat code names and two hardcoded strings in Oni to be translated.

To enable Chinese support, type:

[language]
Chinese = True

This will load a DLL called xfhsm_oni.dll (provided with a Chinese copy of Oni in order to load the Chinese font that also comes with it).

Here are the strings that you can replace using the .ini file:

INI name Description
blam Replaces body text of the Blam window.
damn Replaces title of the Blam window.
savepoint Replaces string "Save Point" in Load Game menu (see "Locales" below).
syndicatewarehouse Replaces string "Syndicate Warehouse" in Load Game menu (see "Locales" below).
nameofcheat_on/_off Replaces name of the built-in cheat code as it appears on the Data Comlink screen when code is entered. E.g., "behemoth_on=Gojira Desu!".

Locales

In order to use the "savepoint" and "syndicatewarehouse" settings above, you must create a locale:

1. Add a setting called "language" under the daodan.ini's [language] section with the name of your locale, e.g.:
[language]
language = xx
You can call the locale whatever you want and it need not be an official ISO locale code such as "en" or "pt", but here's the list of language codes if you want it.
2. Create a folder alongside the Daodan DLL called "daodan_locales".
3. Create an INI file inside called xx.ini (or whatever you called your locale in step 1).
4. The contents of the INI should be:
savepoint = translation
syndicatewarehouse = translation

The next time Oni runs, you should see your translated strings in the Load Game screen. This approach allows you to create/download as many locale INIs as you want, place them in daodan_locales, and switch between them by changing the "language" setting in daodan.ini.

Configuration

Creating a plain-text file called "daodan.ini" in the same directory as the Daodan DLL will allow you to configure which patches are enabled, as well as to store configuration settings and language items. This file is typically created by the Daodan DLL the first time it loads.

On modern versions of Windows (starting with Windows Vista), Oni does not properly request write access to the directory containing Oni.exe (i.e. C:\Program Files (x86)\Oni in typical installs). Windows detects this, and creates a dedicated directory for Oni.exe (and thus the Daodan DLL) to write its files to, located in C:\Users\<Your Username>\AppData\Local\VirtualStore. The directory for Oni will mirror its relative path on disk, so in a typical install it will be at VirtualStore\Program Files (x86)\Oni. This is where all files output by the program (startup.txt, persist.dat, key_config.txt, etc.) will be located when Oni is not run as an administrator. This is the location where daodan.ini must be placed if Oni is to be run as a non-administrator. Note that you can create your own folder for Oni, e.g. C:\Games\, to avoid this permissions issue.

Inside of the daodan.ini file, each configuration setting is stored inside a section as a name-value pair. To temporarily disable a setting in the INI, add a '#' to the beginning of the line and the Daodan will ignore it. Any settings not listed in the INI will use their default values which are listed in § All configuration settings. To change a setting away from its default, add the setting to the relevant section. If the section does not yet exist, add it to the end of the file and add relevant entries under it. Entries are case-insensitive and spacing does not matter.

Here is a simple example of a daodan.ini file:

[devmode]
highres_console = True
showtriggervolumes = True

[gameplay]
cooldowntimer = False

daodan.ini may contain the following sections:

  • devmode (Developer Mode Configuration)
  • gameplay (Gameplay Configuration)
  • graphics (Graphics Configuration)
  • language (Language Configuration)
  • modding (Modding Configuration)
  • oni (Original Oni Options Configuration)
  • windows (OS Interaction Options)

For information on all possible settings, see § All configuration settings.

Command-line arguments

Command line options for the Daodan DLL can also be used when launching Oni, although the syntax is a little different (and a bit more powerful). The basic syntax for a command line option is this:

-<ini section>.<option> <value>

For example, to disable sound start Oni with this:

oni -options.sound false

When <ini section> is omitted, it is assumed to be options. When <value> is omitted, it is assumed to be true unless <option> starts with no (eg. nosound) in which case it is assumed to be false. So an easier way to write the above command would be:

oni -nosound

Options or patches specified on the command line take precedence over options specified in daodan.ini so that you can temporarily override the usual settings. Currently Oni's command line parser isn't powerful enough to parse Language settings (no support for quoting arguments); this will be fixed in a later release.

All configuration settings

Below are the names of the configuration settings you can turn on and off in daodan.ini (names and sections are case-insensitive). Also noted is whether the DLL has this patch turned on or off by default.
