I'm assuming the Mega SG is being made in china. With it having the same price point as the SNT, I wonder if they took into account the 25% tariffs that go into effect at the beginning of next year.

I ordered 2 carts from them last weekend and they showed up today. The physical/label quality of them is very nice. Thus far the games on them have been functioning as expected on the Super NT, including saving. I opened them up to see what the boards looks like, both have the same board. I don't have enough knowledge of electronics to answer your voltage question, but here are scans of the board. Perhaps someone can use these to provide you an answer.

Mine doesn't have the switch
