A couple of details interest me. Don't necessarily mean it's fake or not - they could probably all be attributed to Menavision. I'm still on the fence. But I just find details interesting.
First, the box is taller than the insert. I imagine the insert would fit loosely in that box. Vertically, anyway.
Second, the insert looks like it's in two pieces. The smaller piece touching the cartridge doesn't look like it was cut evenly - there's a bit of a wave to its edges.
There are also some art differences.
One, the box artwork has been stretched horizontally, when compared to the cartridge art.
Also, the lasers coming from the large UFO at the bottom. The ones on the box shooting downward are white, yet on the cartridge and on other photos of the cartridge online, they're red.
