- Subpages: Daodan DLL change log
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.
- 1 C-Daodan
- 2 FASM-Daodan (old)
- Windows XP patch - Fixed Oni crashing at startup on modern computers.
- Windowed mode - Oni can run inside a window properly.
- Custom screen resolutions - Includes many more default screen resolutions.
- BGRA32 (ARGB8888) support.
- Extra cheats - see "Added cheat codes" section below.
- Cheats always enabled; no need to beat game first.
- Extra command line options (for advanced users) - For a list, type "Oni -help".
- DirectInput is used on NT, XP and Vista - Better support for keyboard layouts.
- AIs have ability to properly dodge projectiles.
- Stops fly-in character portraits from being stretched when playing in widescreen.
The DLL enables Developer Mode; go to the pause screen (F1) and type "thedayismine" or simply 'x' to activate it.
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
To enable Chinese support, type:
[Language] Chinese = True
This will load a DLL called xfhsm_oni.dll (apparently provided with Chinese copies of Oni).
Here are the strings that you can replace using the .ini file:
|blam||Replaces body text of the blam window.|
|damn||Replaces title of the blam window.|
|savepoint||Replaces string "Save Point" in Load Game menu (not working?).|
|syndicatewarehouse||Replaces string "Syndicate Warehouse" in Load Game menu (not working?).|
|nameofcheat_on/_off||Replaces name of the built-in cheat code as it appears on the pause screen when code is entered. E.g., "behemoth_on=Gojira Desu!".|
Creating a 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.
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 Daodan.DLL) to write its files to, located in C:\Users\<Your Username>\AppData\Local\VirtualStore. The directory for Oni will reflect 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.
Inside of the Daodan.ini file, each configuration setting is stored inside a section as a name and value pair. To temporarily disable a setting in the INI, add a '#' to the beginning of the line and the Daodan will ignore it.
As of Daodan v3.7, configuration entries in Daodan.ini are stored in several different sections. To change an entry, add it 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. If any entry is omitted, it is set to its default value. Entries are case-insensitive, and spacing does not matter.
Here is an example Daodan.ini file. This example sets the devmode section items to their defaults and disables the cooldown timer patch:
[Devmode] highres_console = True showtriggervolumes = True [gameplay] CooldownTimer = False
Daodan.ini may contain the following sections (names are case-insensitive):
- 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 names of all entries, and a brief help, see the "All Configuration Settings" section below for more information.
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:
-<ini section>.<name> <value>
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:
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:
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.

Note: Unsupported by community. 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, however it still contains the basic patches such as the Windows XP fix and the custom cheats.
Download a ZIP containing the DLLs for an experimental (unstable) FASM-Daodan This includes the projectile awareness patch and support for any language (except Chinese and Japanese).
