This is a mistake that I notice people making very often, so I wanted to make a topic to draw attention to it.
The white/gray border pieces that go around the blue/white tiles
have one line of solid black! Both to avoid misleading design, and to remain true to how the set is used in the actual Sega levels from the Master System version, this black line should be on the
inside of the border.
Correct Usage(Black line is touching the blue/white tiles.)
Incorrect Usage(Black line is on the outside, which is also misleading to the user.)
Here is an example in an actual level:
You can argue all you like that "well it shouldn't be solid black in the first place", but the idea was to authentically replicate the actual graphics from the Master System version. And part of that is that there
is a solid black line.
So if you're using this graphic set - remember this guideline to avoid misleading (and arguably incorrect) designs.
Note: The Lemmini version of this graphic set seems to lack the black lines altogether. So this only really holds for the Lemmix / NeoLemmix version of it. For that reason also, just because this guideline isn't followed may not mean there's an invisible black outline if you're playing a Lemmini, or converted-from-Lemmini pack. It's an unfortunate result of this graphic set being independantly created for two different engines, instead of created for one then converted to the other.
