The most foolproof method of altering the engine turned out to be replacing a library that Oni loads at runtime. Originally this was done by placing a library next to Oni.exe called vtuneapi.dll, which contained code written by SFeLi that would replace or patch functions in Oni. This library came to be known as the [[Daodan DLL]]. The code for it was ported from assembly language to C by RossyMiles. Eventually the decision was made to instead replace binkw32.dll (the library for playing Oni's intro and outro movies) because it loaded earlier in Oni's launch sequence. The DLL was later developed by Gumby and then Alloc, fixing more bugs (some of which result from modern computers running a {{Age|2001|1|29}}-year-old game), as well as adding new features. The DLL's features and settings are documented on the page for the DLL linked above. | The most foolproof method of altering the engine turned out to be replacing a library that Oni loads at runtime.

Not long after the Daodan DLL was released for Windows Oni, it was discovered that the Mac versions of Oni still had Dev Mode in them, too. Instead of replacing the Bink Carbon Library that came with Mac Oni, the Omni Group port of the game application to Mac OS X was patched directly with a hex editor. In the fall of 2008, it was discovered that numerous BSL functions and variables that were thought to be removed from Oni for the Mac [[Mac beta|before release]] were still present in the code, and the ones which allowed Macs to run (almost) all scripts written for Windows Oni were "unlocked" by EdT using hex edits. Certain changes made by the Daodan DLL for the Windows version were also carried over to the Mac's [[OMNI|PPC game application]] in hex-edit form with Neo's assistance. Later, these changes were made in source for Feral Interactive's [[FERAL|Mac Intel port]]. | Not long after the Daodan DLL was released for Windows Oni, it was discovered that the Mac versions of Oni still had Dev Mode in them, too.
