We actually discovered in hursit's metal case thread that there have been 2 slightly different sizes of the LCD going way back. So it's not that it's with Round 2, more that it could've happened at any time.
not exactly...
two very minor changes occurred over a year ago.
1. the LCD changed slightly and had a slightly larger metal cage
2. the PCB wasn't as cleanly cut and would sometimes have nubs sticking out on the edges.
in both instances if the case was design to fit tightly around the PCB or the LCD cage it would have fitment issues.
It's unclear what 3D Printed case
@cps2 is using on his kit, I know there are at least 3 different designs floating out there.
the DogP case was the first one, then I made mine (which is what Save your Games sells), and High-Score Saves has another design.
My design should fit properly with all versions of the LCD module, I can't speak to the others though.
