This ultimate form of modding becomes necessary for modders who want to do things the game's code does not currently allow, as well as to fix bugs. Bug fixes were the earliest notable achievement in engine patching, originally performed by a patching application that altered the PC Oni executable directly, but a revolution in this type of modding occurred in 2006 when Developer Mode was finally discovered in retail Oni's code, and a means for unlocking it was needed. The most foolproof method of altering the engine turned out to be replacing a library that Oni loads at runtime. Now known as the [[Daodan DLL]], this library-as-patch can alter many aspects of Oni's behavior. This allows the fixing of bugs (some of which result from new computers running a {{age|2001|1|28}} year old game), as well as the adding of new features. (All changes made by Daodan are documented [[AE:EXE|here]].) | This ultimate form of modding becomes necessary for modders who want to do things the game's code does not currently allow, as well as to fix bugs.
