[quote=97474]Are you referring to your previous post compared to the OP? If not, share.

I can’t get any of the custom shaders to work in either of my name emulators. I’ve set the x2 horizontal scalene internally. It’s ok but not as nice as what I setup for retroarch.

I completely replaced the instructions in the OP with a new set of instructions and a new method. I’m now recommending that a scanline overlay be used in lieu of shaders. I provided my rationale in the OP, along with my scanline overlay and instructions for use. This will also work with other emulators and should work at different scales. Enjoy :)
