Enable Incest Patch

You can easily enable incest in the game as shown below:

A file named imma.degenerate needs to be in the same folder as OBF.exe.​
  • It does not need to contain anything.
  • It must be the same folder as OBF.exe.
  • The filename is imma and the extension is degenerate.
It doesn’t matter what creates the file, it should work as long as the filename/extension is correct.

In the folder where OBF.exe is located, create a file called imma.degenerate (be sure to enable show file extensions if you’re using Windows explorer). The file does not need to contain anything.​
Command Prompt:
In the folder where OBF.exe is located, type echo. > imma.degenerate and you’ll be all set.​
Command Prompt (PowerShell) :
In the folder where OBF.exe is located, type New-Item -Path . -Name "imma.degenerate" -ItemType "file" and you’ll be all set.​
I’m not sure how long this will work and I think it would be best for all of us to not mention it on Patreon (or DH’s Discord) especially.​
This works with the Steam version as well but if your Steam library is in Program Files, you’ll need administrative rights to create the file on Windows 10. Please follow the Steam instructions below if you need help.​
For Steam, this gets a bit more complex because of the higher security present in Program Files.​
  • Open a “Command Prompt” or “Command Prompt (Powershell)”, you’ll need to run either as Administrator. (NOTE: Windows Terminal generally won’t let you start an Administrator session).
  • Depending on your settings, you’ll may get a elevation prompt. Accept it to continue.
  • The following step assumes the default location for the game folder. If your Steam library is installed somewhere else you’ll need to use the correct path: pushd "%SystemDrive%\Program Files (x86)\Steam\steamapps\common\Breeders of the Nephelym Alpha" (Powershell: cd "$Env:SystemDrive\Program Files (x86))\Steam\steamapps\common\Breeders of the Nephelym Alpha")
  • Now you just need to create the file: echo. > imma.degenerate (Powershell: New-Item -Path . -Name "imma.degenerate" -ItemType "file")
  • Close the command window/powershell: exit
The patcher will eventually return with support for this for a few reasons:​
  • There’s no telling how long this will work and we may be back to patching soon.
  • If people use a patcher for something so simple it may help hide this from Patreon from that much longer.
  • Some users may just find it it easier. Obviously if it’s using the file method, it will not actually be doing any patching at all. Just creating (or removing) a file as directed.
  • The patcher is, unfortunately, not my highest priority at the moment.
