How to change the crosshair hands?

[WALP]

Hello I not 100% sure how this works as I havent tried it myself but I believe it goes like this:
You find the location of the picture of the amnesia hands.
Then you make a copy of the folder it is in in your conversion and you place the penumbra hands picture in there, these hands must also have the same name as the amnesia ones.
Then you edit the resources.cfg for your conversion so that it will give your folder priority resulting in it using your penumbra hand instead.
