I added a shader called sharp-bilinear-simple that does an automatic integer prescale for sharp pixels with minimum blur.
Some explanation of the shader is here:

If you want to try it, you can download the file from here (right click, save as...):
https://raw.githubusercontent.com/rs...-simple.shader
and enable it in fs-uae launcher by adding a line
Code:
shader = <your_path>/sharp-bilinear-simple.shader
in the advanced config textfield.
