What you you mean by you can't get a one pixel border to work? What tools are you using to generate your sprite sheets?
when i set border to 1 i get an error regarding the sprite
the error goes away when i increase the resolution of the sprite
here are some images explaining it better
the image corona needs when border set to 1:
the image Pyxel outputs:
corona expects a 2 pixel border when border is set to 1
1 pixel for every tile means 2 pixel border if 2 tiles next each other
else i get this
