adobe photoshop - 1bit MacPaint style Dithering

I am looking for a way to achieve a MacPaint style effect from a full color RGB piece. See below for an examples of the style.

Basically what I need is a way to assign a different 1bit patterns to different color values (alternatively to a different grey values) in photoshop, or some other windows software (I have found HyperDither that seems to be able to do that, but it is MacOS only).

The piece I am using it on is just few objects against dark background, but because the objects rely heavily on gradients, doing it by hand would take forever.

Thank you in advance.

If you want control over the actual patterns used you could define actual patterns in Photoshop and use them as pattern fills. There're a number of ways you could apply the pattern fills... one idea which may or may not work for you is to use actual fill layers with blending options...

Take this for example:

Convert the image to grayscale and posterize it (with as many levels as you want patterns):

Create a pattern fill layer (for this example I literally copied the MacPaint pattern swatches and turned them in to patterns). From the pattern fill's layer style dialog, drag both the "Underlying Layer" sliders under the "Blend if" so that the pattern is only visible if it is over a certain range of gray:

Repeat with more pattern layers:

The "Blend if" method gets a bit tricky with more than a few layers since you end up with the patterns blending with each other so that may not work for you.

Another option is to create a bunch of 1 bit masks to apply to each pattern fill layer (you could do this by running a threshold on your image at different levels). Something like this...
