Those inspirations happen a lot. In fact some believe that things from the old Zelda cartoons inspired certain features of later Zelda games. Back on topic, I wondered why the Bros were working at a general store. I thought perhaps where they lived, plumbing wasn't enough to pay the bills or something.
I don't think either of these OVAs will ever be brought to the States, or anywhere else outside Japan for that matter. And if Nintendo ever considers to dub them, they'd probably only dub the Snow White one. The other two fairy tale retellings, from what I've read, either has guns (I don't think Nintendo would aprove of rereleasing an animation that has someone from a family friendly game series threatening someone else at gunpoint. Look at "Legend of Dratini") or content that many outside Japan would not understand. If you ever wondered why most dubbed anime is not as good, it's because the companies that dubbed the eps had to take certain material out due to cultural differences.
Nonetheless, I still wanna see the whole thing on better quality screen, subbed.
