How do you apply the injectors without crashing DOA6? It's easy, I'm just explaining it carefully, baby step by baby step.
1-Download the Reshade app over
https://reshade.me/ then install it.
2-It will prompt you to select the executable. Go to wherever you installed the game, somewhere like "C:\Program Files\Steam\steamapps\common\Dead or Alive 6\" then click on DOA6.exe.
3-Then select the DirectX version by clicking on D3D10+ because it's a DX11 game. Then click ok. The directories prompt will appear, but you can just click OK because you'll adjust things later (please keep track of the very few files put in the "Dead or Alive 6" bin by the installation).
IF...it was like DOA5, you'd be done, only needing to download a injection preset somewhere like
http://sfx.thelazy.net or just make your own preset. But the game is protected against it, so you'll need the fix files to make it all work from somewhere outside the folder of the game.
4-Download the fix zip file at
http://helixmod.blogspot.com/2019/03/dead-or-alive-6.html and extract it anywhere, besides the game folder.
5-Cut all the files made by the Reshade installation and paste them inside Helix's folder.
6-Open with the Notepad app the d3dx.ini file then edit it. Press Ctrl+F and search for the "
;proxy_d3d11=reshade.dll" line and delete the semicolon. Save and close this file.
7-Rename the dxgi.dll to reshade.dll.
8- Finally open 3DMigoto.exe, preferably as administrator. You'll see the Reshade overlay if everything is OK.
